51 Easy Math Riddles for Kids to Make Math Learning Fun

Many children say math is boring. You can argue, but it really is, assuming that students spend their time in math classes yawning at the chalkboard.

But you can make math a bit funnier and cheer kids up before homework or math classes using fun riddles. Check these 51 simple math riddles for kids and discover their advantages for the learning process.


Before we start

If your kids enjoy riddles, they will inevitably love math because riddles make learning easier. Riddles alone are not enough to learn math, however tutors often use riddles to help kids remember math concepts easier.

Before we get into math riddles, it’s important to mention that personalized tutoring is one of the best ways to help your child understand math quicker.

Math riddles benefit studying in many more ways than just making the process funnier thanks to their non-standard, creative, and tricky nature. Check four benefits that math riddles provide:

Maths Riddles for Kids Develop Logical Thinking

In essence, any math riddle is a logical problem that requires some calculations to get a solution. Additionally, riddles challenge the traditional understanding of math. That’s why such tasks foster students to think outside the box to find solutions.

We take this “out-of-the-box” mindset for granted as it’s something holistic, but it blends creative thinking and logical skills.

A student develops logical thinking while seeking alternative ways to solve a math problem and addressing their life experiences. On top of that, children learn to find references between math problems and real-life situations.

Math Riddles Improve Kids’ Concentration

Solving a math riddle requires a student to concentrate on the matter entirely. Children switch off reality in the solving process, recreating the given situations in their minds and recalling their memories.

They learn to channel their attention to a single activity, enhancing their concentration capacity in the process.

Math Riddles for Kids Contribute to Mental Flexibility

Students often learn specific rules to solve math problems. If none of these methods works, children begin to struggle.

They see the door and shuffle available keys, but none of them fits the lock’s hole – what’s the problem? But what if the door is already open, and all you need to do is pull the handle?

Let’s take a fun riddle about a circle as an example: The circle has sides. What are they?

Wait, but the circle is round. Consequently, it has no sides. Therefore, the riddle is wrong. But if you step out of a traditional mindset, you will guess that the circle has two sides – inside and outside.

By solving such riddles, your child develops mental flexibility – the ability to shift thinking patterns to adapt to different situations. This skill goes way beyond math as life can generate countless outcomes you will have to face every day.

Riddles Raise Metalinguistic Awareness

Riddles are essentially language manipulatives – they tell about real life using metaphorical words. Solving math riddles means decoding metaphors and comparisons. Riddles help kids grasp language more deeply and find similarities between allusions and real-life situations.
