As a child, I would spend hours putting together puzzles… whether it was 3-D puzzles or figuring out a crossword. I also loved it when teachers would give the class an open-ended question and we had to work in groups to figure out the answer in our own way.

Even something as simple as playing checkers with my brothers gave me the chance to use strategy as a way to win the game. I honestly believe that it’s so important for kids to solve problems at a young age, as it helps them think critically and outside the box.

Table of Contents

## So, Why Is It Important To Teach Kids Problem Solving?

I think these kinds of activities are so important for kids to do because it helps them learn how to think analytically and solve problems on their own. It's a great way to get kids to use their imaginations and be creative.

Rote memorization simply does not have the same effect. This type of learning is great for learning facts like historical dates, but it’s not going to help kids figure out how events in history happened and the results.

We take these problem-solving skills into college, the workforce, and travel . My ability to problem solve since childhood has certainly got me through many sticky situations while in a new city or country.

Additionally, problem-solving helps children learn how to find creative solutions to challenges they may face both in and out of the classroom . These activities can also be fun and used in cohesion with school or playtime.

## 17 Fun Problem-Solving Activities for Kids

1. marble mazes.

This activity was selected because it requires them to think spatially. Spatial learning will benefit kids when they start driving, riding a bike, playing sports,etc.

To do this activity in its simplest form, you will need a piece of paper, a pencil, and some marbles. First, draw a maze on a piece of paper using a pencil.

Make sure to create a start and finish point. Then, place the marbles at the start of the maze. The goal is to get the marbles from the start to the finish by tilting the paper and using gravity to guide the marbles through the maze.

Another example of a marble maze can involve using toilet paper rolls taped together to create a three-dimensional maze. The larger the maze, the harder you can make it.

Check Price on Amazon!

If you are not into the DIY method, you can always buy a toy maze on Amazon. A good 48 piece puzzle is the Melissa & Doug Underwater Ocean Floor puzzle.

## 2. The Tower Challenge

Building a tower gives kids the chance to think about gravity, structure, and balance.

To do this activity, you will need some building materials like legos, blocks, or even toilet paper rolls. The challenge is to see how high they can stack the materials without the tower toppling over.

This can be done individually or in teams. An activity like this is good for younger kids and is the building block to learning about harder topics like engineering.

## 3. The Egg Drop Challenge

The egg drop challenge helps kids learn how to engineer a solution that prevents something from breaking. It requires them to think critically about which materials will best protect something fragile like an egg when dropped from a height.

To do this activity, you will need some eggs and various materials such as straws, cotton balls, bubble wrap, etc. The goal is to construct a device that will protect an egg from breaking upon impact.

This can be done individually or in teams . Teams can even have a competition for the best egg drop device.

As children begin handling, shopping for, and cooking their own food, activities like this will help them understand how to handle breakable items like bottles, eggs, delicate fruit,.etc. Ideally, this is best for age groups 8 and up.

## 4. The Penny Drop Challenge

This activity was selected because it requires kids to think about physics and how different materials affect sound.

To do this activity, you will need a penny ( or another coin), a cup, and various materials such as paper towels, cotton balls, etc.

The goal is to drop the penny into the cup without making any noise. Begin by placing different materials into the cup and then drop the penny into it. The children should also drop the penny from different heights into the same material to see if/how the impact from a higher drop affects sound.

Group kids into teams or let them try it on their own.

Kids should make note of what type of sounds are made when the penny hits different materials. This is a great activity for kids who are interested in science and physics.

## 5. The Balloon Race Challenge

This activity was selected because it helps kids learn about aerodynamics and Bernoulli’s principle . It also requires them to think creatively about how to design a balloon-powered vehicle.

To do this activity, you will need balloons, straws, masking tape, and markers. The goal is to design a balloon-powered vehicle that can travel a distance of at least 10 feet. Kids can begin this activity by sketching out their designs on paper.

After they have a basic design, they can begin building their vehicle from various materials. Then kids can explain why they think the balloon traveled or did not travel as far as it did.

## 6. The Marshmallow Challenge

Marshmallows are not only delicious, but they are also soft and malleable. So kids can have fun using it for some construction projects.

This activity was selected because it requires kids to think creatively about how to build a structure using limited materials. It also helps them learn about engineering and work as a team.

To do this activity, you will need marshmallows and spaghetti noodles. The goal is to build the tallest free-standing structure possible using only marshmallows and spaghetti noodles. If you don't have spaghetti noodles, use something similar like pretzel sticks.

You may even want to establish certain rules like each team can only use a certain number of marshmallows or noodles. A time limit can also make it more fun and challenging.

For more fun activities, check out our post on problem solving exercises for team building .

## 7. The Balloon Pop Challenge

If you remember your childhood, you probably remember popping balloons for fun at times. But this activity is different because it requires kids to use strategy and critical thinking.

This activity was selected because it helps kids learn about patterns and problem-solving. It is also a lot of fun for kids who like popping balloons. The goal is to create a device that will allow them to pop a balloon without using their hands.

To do this activity, you will need balloons and various materials such as straws, string, paper clips, etc.

## 8. Picture Pieces Puzzle Game

As mentioned earlier, puzzles are a great pastime – especially in childhood. Kids must think critically about how to put the pieces together to create a certain picture. It also helps them learn about shapes, colors, and other concepts.

You can take a medium to large picture and cut it into pieces. If you have younger kids, you may want to make the pieces larger. However, if you have kids closer to the 8-11 age range, you should be able to provide a challenge and make the pieces smaller.

## 9. Copy the Block Model

For this challenge, you can build a model out of blocks for the kids to copy. Put kids into groups and make sure each group has the same number of blocks you used for your model.

Make your model block as simple or complex as needed for your child's age group.

Set a time limit and make sure each group starts at the same time.

## 10. Team Scavenger Hunt

A scavenger hunt is great for kids because they have to search for items and use investigative skills. It is also a lot of fun and can be done both indoors and outdoors .

To do this activity, you will need to create a list of items for the kids to find. The items can be anything from common household items to things you would find outside.

These types of activities can also revolve around a theme like a holiday, movie, or book. For example, if the kids are fans of “Harry Potter” you can make a list of items to find that are related to the movie.

## 11. Obstacle Course

This activity requires kids to think creatively about how to get from one point to another while maneuvering around obstacles. If you have outdoor space, this can be done with common objects such as hula hoops, cones, etc.

If you don't have access to an outdoor space, you can use common household items to create an indoor obstacle course. For example, you can use chairs, blankets, pillows, etc.

Begin by setting up the course and then timing each child as they complete it. You can also have them race against each other to make it more fun.

Obstacle courses are also great because kids get to be physically active while they are thinking critically.

## 12. Reading Storybooks

There are many great benefits for kids that read storybooks. One of the excellent benefits is the ability to problem-solve. When they read the stories in the books, they see scenarios that cause them to be attached to the various characters they read about.

So, when they encounter a real-life problem, it is often productive to ask a child how their favorite character would solve that problem. Your kids can also be encouraged to come up with various options and possible outcomes for some of the situations they may encounter.

This not only helps kids solve various problems but become more independent as well.

## 13. Ask Them Open-Ended Questions

A good way to improve a child's ability to think critically and creatively and improve their ability to solve problems is by asking open-ended questions. It also helps them to develop healthy personalities .

There are no right or wrong answers to these questions. In addition, the solution requires more than a simple “yes” or “no” answer. Furthermore, it allows kids to put some extra thought into their responses.

Here are some examples of open-ended questions you may want to ask.

- What did this experience teach you?
- Was this easy? What was easy about it?
- What this difficult? What is complicated about it?
- What may happen next in this situation?
- How did you come to this solution?
- What, if anything, would you do differently next time?
- What can we do to make things more fun next time?

## 14. Build Various Structures with Toys

Whether wooden blocks, LEGO blocks, or engineering blocks… giving your kid blocks to build whatever their minds can dream up is fun. In addition, it requires them to think about how they will make a structure, put the pieces together, and creatively ensure the building's function and design.

You may also want to challenge them to build something more complicated and watch them use their brain power to make it happen.

## 15. Acting Out Skits

Impromptu activities like acting out skits help kids identify problems, develop solutions, and execute them. This process works with multiple kids being divided into teams.

First, you will want to write down different situations, such as resolving a disagreement between siblings or dealing with bullying on the playground on a piece of paper. Second, you will fold the paper and place it in a hat or bowl.

Third, each team will pick a scenario out of the hat. Finally, you can give the kids a few minutes to discuss their solution and act out.

## 16. Solving Moral Dilemmas

In this simple game, you will help your kids solve simple dilemmas they may find themselves in. You could write down a situation your child may find themselves in and help them learn the moral way to solve the problem.

For instance, “The cashier gave them an additional $5 change back on my purchase. What should they do?” Another scenario could be, “I saw my friend cheating on a test. Should I tell on them or let it go?” A third one could be, “I caught my friends stealing some gum from the store. What should I do?”

After writing down the dilemmas and placing them in a bowl, get each child to select one and read it aloud. Finally, you will help them devise morally correct solutions to the moral dilemma.

## 17. Animal Pairing Game

This is a fun and creative game to help your kids with focus, critical thinking, and team building skills . In addition, this activity requires an even number of players to participate (4, 6, 8, etc.)

Before starting the game, you will want to write the names of different animals twice, each on a separate slip of paper. Then pass out the slips of paper to each individual or team member, instructing them not to share with anyone the name of the animal they received.

Then the children will perform activities the animals might do without talking or making sounds. Some of these activities might include:

- The way the animal cleans or grooms itself
- The way the animal sleeps
- The way the animal fights
- The way the animal eats or drinks
- The way the animal walks or runs

The goal is for each child to successfully pair up with the other child who has selected the same animal.

## How Problem Solving in Childhood Helps in Adulthood

Children are not born with problem-solving skills. It is something that needs to be learned and developed over time .

From babies who learn how to communicate their needs to toddlers who figure out how to get what they want, to children who are starting to understand the consequences of their actions – problem-solving is a process that begins in childhood and continues into adulthood.

Some of the benefits of teaching problem-solving skills to children include:

- Improved critical thinking skills
- Better decision-making skills
- Enhanced creativity
- Improved communication and collaboration skills
- Increased confidence

There are many ways to teach problem-solving skills to children. The activities mentioned above are just a few examples. It is important to find activities that are appropriate for the age and abilities of the child.

With practice, children will develop these skills and be better prepared to face challenges in both childhood and adulthood.

## Final Thoughts About Fun Problem Solving Activities For Kids

## Math brain teasers for kids

Sometimes keeping your students engaged during a (long) school day feels like a losing battle. How do you gain their full attention while teaching the skills they need to succeed? How do you turn tough and intimidating concepts into fun, entertaining lessons that actually spark life in the classroom?

Brain teasers for kids are a great form of game-based learning that not only entertain children but also inspire some creative thought in the classroom. People of all ages can indulge in these playful — yet challenging — activities.

And some examples of when teachers might want to use brain teasers are on a bulletin board in the classroom, as a partnered activity to start a new concept or lesson, or during a rainy day indoor recess box.

We’ve gathered 45 examples of brain teasers for kids with answers, organized by category:

Table of Contents

Language brain teasers for kids :

Riddles ; Language associations ; Lateral thinking problems.

Math brain teasers for kids :

Math riddles ; Pattern problems ; Prodigy.

Visual brain teasers for kids :

Spot the difference ; Rebus puzzles ; Optical illusions ; Stroop effect test.

Use the list below to find the perfect brain teaser for your class!

## What are brain teasers?

Before you explore our examples, you might be wondering what brain teasers actually are.

Cambridge Dictionary defines a brain teaser as “a problem for which it is hard to find the answer, especially one which people enjoy trying to solve as a game.”

Brain teasers are a type of puzzle — and as the list below reveals, they come in many different forms. Often presented as a riddle, question or activity, brain teasers require a little extra brainpower to solve.

It's important to note that if you have any English language learners in your class, brain teasers for kids might pose a challenge for them. If that's the case, they might need you to walk them through the brain teaser more closely, or you can find ones that better suit their language level.

Brain teasers for kids differ from other complex or abstract problems because they’re usually done for fun. Although you can use them to analyze problem-solving and critical thinking skills, they’re often used as an amusing activity to encourage logical and lateral thinking , or thinking “outside the box.”

## 3. Lateral thinking problems

Lateral thinking problems require creative thinking with an indirect approach.

These questions require logic and careful thought to solve. The most notable example of a lateral thinking problem is the classic Monty Hall problem .

Here are two examples of lateral thinking problems kids can try to solve.

a) The river crossing problem

Image source: Popular Mechanics

A farmer is travelling with a fox, a goose, and a bag of beans. During his journey, he comes across a river with a boat to cross it.

The farmer can only fit one thing in the boat with him at a time. If left alone together, the fox will eat the goose or the goose will eat the beans. How does the farmer get everything across the river safely?

b) The light bulb problem

There are three light switches outside of a room-- labeled number one, number two, and number three. The door to the room is closed and you can’t see in. All three switches are off.

You need to figure out which switch belongs to which bulb. You can use the switches however you want to, but can only enter the room once. How do you do it?

a) Here’s the step-by-step solution:

- The farmer brings the goose across the river first (if he leaves the goose alone, it will either eat the beans or be eaten by the fox).
- The farmer brings either the fox or the beans across and leaves the other one alone.
- Now the farmer has two items on the other side of the river, including the goose. If he leaves the goose again, the same problem will occur. So, the farmer must bring the goose back to the other side.
- The farmer brings the other item back (either the fox or the beans) and leaves the goose alone again. The fox and the beans are now on the other side of the river.
- The farmer returns and brings the goose across the river again.

b) Turn on the first switch and leave it on. Turn on the second switch for a few minutes, and then turn it off again. When you enter the room, one light bulb will be on. You’ll know it goes with switch one because you turned it on. Another bulb will be hot. You’ll know that goes with switch two because it was on for a little while. The bulb that’s off and cold goes with switch three because you didn’t touch it.

Like math puzzles , these brain teasers for kids can increase engagement with math content and inspire your students to work on math concepts and problems outside of regular lessons.

## 1. Math riddles

These riddles are just as amusing as the ones above, but they’re math-focused . Use them to give students some extra math practice and encourage resourceful thinking.

Math riddles

a) Divide 30 by ½ and add 10. What’s the answer?

b) A clerk at the butcher shop is six feet tall and wears size 10 shoes. What does he weigh?

c) A farmer has 19 sheep on his land. One day, a big storm hits and all but seven run away. How many sheep does the farmer have left?

d) Your sock drawer only contains 18 white socks and 18 blue socks. How many times do you need to reach inside the drawer and take out a sock to guarantee a matching pair?

e) You planted sunflower seeds in your back garden. Every day, the number of flowers doubles. If it takes 52 days for the flowers to fill the garden, how many days would it take for them to fill half the garden?

f) Using only addition, how can you use eight eights to get the number 1,000?

g) When Ashley was 15, her mother was 37. Now, her mother is twice her age. How old is Ashley?

a) It's 70. You’re dividing 30 by ½, not by two. Thirty divided by ½ is the same thing as multiplying it by two, which is 60. Plus 10 makes 70!

b) Meat. He works at the butcher shop, so he weighs meat for a living.

c) Seven. The riddle says all but seven run away, meaning there are seven left who didn’t.

d) Three times. On the third time, you’ll get either a white or a blue sock to match with one of the other two you’ve already grabbed.

e) It would take 51 days. If the number of flowers doubles every day, half the garden would be full the day before, on the 51st day.

f) 888 +88 +8 +8 +8

g) Ashley is 22. Her mother is 22 years older, so when Ashley is 22, she’s now half her mother’s age.

## 2. Pattern problems

These questions require students to identify a pattern before they can answer a particular question. Kids must use creative and logical thinking to find the answers.

## 4 + 4 = 168

5 + 5 = 2510.

b) What makes this number unique: 8,549,176,320?

c) Solve the pattern puzzle below. Find the missing number to replace the question mark.

Image source: Genius Puzzles

d) Solve the following:

Image source: AOL

a) The missing number is 3612. The answer is the number multiplied by itself and then the number added to itself. Six multiplied by six is 36, and six plus six is 12.

b) It contains each one-digit number, zero through nine, listed in alphabetical order.

c) The missing number is 17. Each number in the circle is the sum of the numbers in the opposite quadrant. In this case, the numbers are eight and nine — added together makes 17.

d) The answer is 14 (or 16), if you’re on the other side of the debate .

b) Are the two squares different colours?

Image source: Brain Den

b) They’re exactly the same colour. If you place your finger over the spot where the squares meet, you can see they’re the same. Try this impossible paper puzzle if you want a more hands-on optical illusion. You can make one to show your class, then have students make their own as a fun brain teaser to show friends and family.

## 4. Stroop effect test

The Stroop effect was discovered in the 1930s by John Ridley Stroop. During the test, you’re given a list of colour names, with each word being a different colour than what they describe.

The test involves saying the colour of a word, rather than reading the word itself. Your mind must process the two conflicting pieces of information, which slows down reaction speed and requires careful thought to get through.

## Scientists Have Solved the 141-Year-Old ‘Reverse Sprinkler’ Problem

This brain-teaser has baffled physicists since 1883. Thanks to some innovative engineering, it finally makes sense.

- For 141 years, physicists have pondered a deceptively difficult question—what would happen if a sprinkler worked in reverse?
- Two camps formed—one arguing that a water-sucking sprinkler would have to spin clockwise, and another camp pushing for an counter-clockwise motion.
- Scientists from New York University took care of the problem by designing just such a device, and discovered that a reverse sprinkler would spin counter-clockwise 50 times slower than if it was just a normal sprinkler.

First posed in 1883 by Austrian physicist Ernst Mach and popularized by Nobel laureate Richard Feynman, the “reverse sprinkler” question is relatively simple—if you put an s-shaped sprinkler in a tank of water , and the sprinkler sucked in water, what direction would it spin and why?

But this is where things get tricky. One camp adamantly suggests that the sucking force would pull the nozzle counter-clockwise, while others argue that inflowing water would smack the inside of the nozzle, forcing it clockwise.

“The answer is perfectly clear at first sight,” Feynman wrote in the 1985 autobiographical book, Surely You’re Joking, Mr. Feynman . “The trouble was, some guy would think it was perfectly clear one way, and another guy would think it was perfectly clear the other way.”

To finally solve this 141-year-old problem, scientists from the New York University (NYU) created custom sprinkler devices that pushed and sucked in water at controllable rates. Complete with a new kind of ultra-low-friction rotary bearing, according to the NYU press release , the sprinklers were constructed so the researchers could observe what was going on outside and inside the sprinkler. To capture the reverse sprinkler’s fluid dynamics in action, the team also added dyes and microparticles to help illuminate the waterflow via lasers . The results were published in the journal Physics Review Letters in January.

As the sprinkler sucked in water, the NYU scientists discovered that it created a kind of “inside-out rocket ,” which very slowly rotated the sprinkler counter-clockwise.

When the sprinkler works as intended (a.k.a. spraying water) it effectively acts like a mini-rocket, with the water acting as the propellant that spins the sprinkler. When flowing in reverse, however, these jets meet inside the sprinkler chamber—but don’t smash head-on due to the flow caused by the sprinkler’s curved arms. This slight misalignment causes the sprinkler to slowly rotate in reverse, about 50 times slower than when the sprinkler is operating normally.

“Our study solves the problem by combining precision lab experiments with mathematical modeling that explains how a reverse sprinkler operates,” NYU associate professor and senior author Leif Ristroph said in a press release. “We found that the reverse sprinkler spins in the ‘reverse’ or opposite direction when taking in water as it does when ejecting it, and the cause is subtle and surprising.”

Ristroph and his team didn’t undertake this 141-year-old problem just for laughs. Understanding these fluid dynamics could help us better understand the sustainable sources of energy flowing around us, such as “wind in our atmosphere as well as waves and currents in our oceans and rivers,” Ristroph said.
