Expert tip: Questions to ask

Specifically, I asked Geillan Aly, Founder and CEO of Compassionate Math, what prompts parents can use to inspire their children to explain their train of thought when solving math riddles. She emphasized the need to ask the right questions.

“If you want your kids to explain their thinking, focus on asking questions that get a conversation going.”

Any question you ask should be the beginning of a conversation, so it's best to avoid questions that have one- or two-word answers. Questions that get conversations going are usually how and why questions. Questions you can ask your child to explain their thinking can be questions such as Why did you choose your method?, How is this solution related to (a different solution / idea)? How did you check your work? or Can you write another riddle/problem using this same key/solution method?. Use their answer to get a conversation going

Frequently Asked Questions (FAQ)

What is a good math riddle?

A good math riddle is a problem that requires logic and specific constraints to find a solution. It presents data in such a way that a student needs to identify a non-obvious relationship between numbers or words. 

How do riddles improve kids’ math skills?

To solve math riddles, kids analyze a set of given statements and identify which parts of the data provided are relevant to the final calculation. That’s how employing logic, arithmetic, and problem-solving strategies help children improve their math skills with riddles.

They also support the development of number sense and help students learn to follow multi-step instructions. Besides, introducing mathematical vocabulary and concepts in a format that requires active engagement with the definitions of those terms to find the answer serves well, too.

What are easy math riddles for beginners?

Easy math riddles for beginners focus on basic counting, simple addition, and the identification of shapes. Take this one: ‘You have three coins that add up to twenty-one cents. What are they?’ The answer is two dimes and one penny. 

Or: ‘What can you place between the numbers 5 and 6 so that the result is a number greater than 5 but less than 6?’ The answer is a decimal point, resulting in 5.6. 

Such problems use small integers and common objects to teach beginners how to combine different mathematical facts to satisfy a specific set of requirements.

How to use these math riddles?

The best math riddles can bring many important benefits to children (that I will discuss shortly), but only when used in the right way. To help you maximize the value that your kid gets from these puzzles, I’ve talked with mathematics educator Geillan Aly and asked for her advice.
