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.
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.”
Favorite math riddle
Additionally, Geillan Aly shared her math riddle of the day, as it’s based on the recent 6-7 trend on social media.

| Why was six afraid of seven? | Because seven ate nine! |
Benefits of math riddles
Logical thinking
Fun math riddles for kids encourage creative, logical, and critical thinking, facilitate problem-solving, and allow kids to conduct a critical evaluation of the problem. Later, all these soft skills can be applied in real-life situations.
According to a study published on ScienceDaily, funny math riddles have a positive impact on a child’s success in adulthood and teenage years. The ones who experience riddles perform better in tasks that require rotating and moving shapes, which is an important predictor of STEM success.
But beware, when kids are unable to solve engaging math riddles, they can get easily distracted. To avoid this, try the following techniques:
- Even hard math riddles will become easier if kids read them aloud. This helps better understand the question and grasp hidden clues.
- Rephrasing also works if a child cannot understand what’s required in a riddle.
- For visual learners, drawing out the task can be of much help. The hardest math riddles are often abstract; the extra step will make them concrete.
Concentration
If your child starts solving math puzzles for kids at a very early age, this will reduce the likelihood of problems with concentration in the future. And if they have a small practice each day, you’ll see the benefits of math riddles sooner.
Here’s how math riddles enhance concentration:
- When choosing a math riddle for kids, pick the most interesting exercise, and you’ll see how they forget about everything that could distract them from learning. Yes, even their phones!
- Secondly, solving challenging math riddles requires children to plan steps and move consistently towards a solution. While creating a detailed roadmap, kids also learn to focus on a task for a long time, not just for several minutes.
- Finally, kids’ math riddles train them to hold multiple pieces of information in their minds at once. This strengthens working memory – a key element of concentration.
Flexible thinking
Whether you’re dealing with math riddles for elementary students or aiming to tackle math riddles for middle school, the challenge is always the same: Approach the problem from different angles till you find the right answer.
These tips will help you succeed:
- Riddles are usually based on polysemantic words. While a child tries to find the best-fitting meaning, they also improve their language skills.
- Similarly, solving math riddles easily involves visualization. Thus, children learn to turn abstract things into concrete, at least in their minds.
- If a child works with challenging math riddles with answers but fails to get the correct response, they start understanding that making mistakes is simply a stage of the learning process.
Teamwork
When used in a team setting, you can access other exciting benefits of math riddles for children, specifically, the ability to interact effectively towards a common goal. You can even present them through animated booklets to make collaboration more engaging.
You can also turn the whole thing into a game by dividing kids into two or more teams and setting a timer. Then, count which team manages to solve more of the funny math riddles with answers.
Self-esteem
Last but not least, solving elementary or middle school math riddles may help to improve a child’s self-esteem.
Here’s what you should do to create a positive experience for your kid:
- If they face any problems, you should always be there to back them up. For example, if you asked the riddle or puzzle more than a minute ago with no answer, you can give them some hints. Celebrating an effort is just as important as getting the right answers to those math riddles for young kids.
- At times, ask your child to explain how they managed to solve a specific task. Acting as a teacher helps them feel more valued and important.
- If you find your current math riddles with answers too difficult, skip to simpler tasks. It’s vital to build progress steadily.
Conclusion
Tricky math riddles for kids offer numerous benefits beyond making math classes or homework enjoyable. While solving puzzles and brain teasers, children of all ages develop math reasoning and analytical skills, learn to think outside the box, and improve concentration. To diversify your child’s math routine, you can take some of these 56 math riddles and have fun together.
