Math Riddles for Kids

Updated
Do you think your child could ace these math riddles?

There was a time when math was taught by presenting a child with a page of equations and having them sit and work out the answers. Thankfully, math is now taught in a more engaging way, and math riddles are one of the tools used to achieve this.

But did you know there are more benefits to math riddles for kids than solely being able to crunch numbers at a faster pace?


The Benefits of Math Riddles for Kids

Math can be frustrating, but math brain teasers for kids can also result in a variety of benefits.

They can help your child:

Learn About Language

Language skills may not be the first thing you think of when you are considering math riddles for kids. However, the wording of math riddles is often critical to the ability to solve them, so working on them can help your child pay closer attention to words, their meanings, and their flexibility (1).

Bond With Parents

Any activity that encourages parents and children to spend time together, interacting and discussing ideas, can help to strengthen bonds.

Strengthen Basic Math Skills

Most math riddles for kids require basic math skills, such as addition or multiplication. Using these skills in the more creative context of riddles, rather than through pages of equations, can also be more fun, and less intimidating.

Promote Creative Thinking

When you ask your child a riddle, finding the answer is not as simple as repeating a fact they have previously learned. Instead, they have to form associations between pieces of information, link ideas, and use the facts they have to reach a conclusion (2).

Easy Math Riddles For Kids

Easy riddles are an excellent way to get your math-phobic child engaging in math. They are also a wonderful way to flex your own brainpower if it has been a while since you last had to explore a math problem.

Then, once your children discover math can be more fun than reciting bland facts, you may both start to enjoy yourselves.

Challenging Math Riddles For Kids

If your child is already a bit of a whiz at math, break out these more challenging math riddles. One word of caution though — be sure to read through the question and answer before giving them to your child.

That way you’ll be able to discuss the riddle answering process and the answer itself, with confidence.

A zoo has 100 pairs of animals. If two pairs of babies are born for every one of those original animals, and then, rather sadly, 23 of those animals die, how many animals are left in the zoo?

977. Here’s a breakdown.

  • 100 pairs of animals = 200 original animals.
  • 2 pairs of babies born for each original animal = 4 babies for each animal = 800 babies.
  • 800 babies plus the original 200 animals = 1000 animals in total.
  • 23 animals die = 1000 – 23 = 997 animals.

Dana’s friends are throwing her a birthday party. The friends spend half of their money, plus $2 on the cake, half of what they had left, plus $2 on food, and half of what they had left plus $1 on drinks. Now they are out of money. How much did they have to start with?

A bag of candy weighs one pound plus half of the weight of the bag. How much does the bag of candy weigh?

If you said 1.5 pounds, you are wrong! The bag weighs two pounds. Because the bag of candy weighs one pound, plus half of a bag, the one pound gives us the weight of the other half of the bag. As half a bag weighs one pound, the entire bag weighs two pounds.

A farmer has a farmyard full of chickens, all of whom are laying lots of eggs. The farmer decides to give away the eggs to some friends and wants to give them all the same number of eggs. The farmer figures out they must give seven friends eggs, otherwise, there will be one egg left over. What is the lowest number of eggs the farmer needs for this to be true?

301 eggs. The total number of eggs must be one more than a number that is divisible by 2, 3, 4, 5, and 6. That is because each of these numbers leave a remainder of 1.

If that’s true, one less than the number must be divisible by 5, 4, and 3.

5 x 4 x 3 = 60.

Then you just must find a multiple of 60 so that 60 x n + 1 is divisible by 7.

61/7, 121/7, 181/7, and 241/7 all leave remainders, but 301/7 does not.

There are seven children on a bus. Each child has seven backpacks. In every backpack, there are seven large cats. For each large cat, there are seven small cats. How many legs are on the bus — not including the driver?

10,990 legs. Here’s a breakdown.

  • Seven children each with seven backpacks = 49 backpacks.
  • Seven big cats in each backpack = 49 x 7 = 343 large cats.
  • 4 legs for each large cat = 1,372 legs.
  • Seven small cats for each large cat = 7 x 343 = 2401 small cats.
  • 4 legs for each small cat = 7 x 2401 = 9,604 legs.
  • 2 legs for each child = 14 legs.
  • 1,372 legs + 9,604 legs + 14 legs = 10,990 legs.

What is the next number in the pattern — 1, 11, 21, 1,211, 111,221, 312,211?

13,112,221 — When you say the number aloud, it describes the number before it, so 1 = One, one, which is written as 11, then you have two ones = 21 and so on.
