How many can you solve? Brain-flexing math riddle quiz (31–40)
Math problems that elementary schoolers can solve but adults surprisingly can’t
This is a problem from Nada Junior High School’s 2018 entrance exam.
It’s a difficult question, but I’d like to introduce it to parents whose children want to attend a prestigious junior high school.
It’s the kind of problem that many adults surprisingly can’t solve, which really shows how important flashes of insight are.
How about using it as brain training for your child?
A simple problem that even elementary school students can solve in 10 seconds
Even among elementary school students, there are probably many who struggle with area problems, right? It’s hard to understand even when it’s explained.
But there’s a trick to solving area problems: once you memorize it, you can solve them easily.
In this problem, we’re finding the area of a triangle.
To solve it, you need to know the exterior angle theorem—also known as the “slipper rule”—and remember the steps.
Math can seem difficult, but in reality, many problems are easy to solve if you’ve got the rules and procedures in your head.
For this problem, once you get used to it, I think you could solve it in tens of seconds!
Fun Math
It’s a quiz that lets you enjoy bonding with children through riddles.
It also helps them understand that math can be used to read clocks, making it both educational and fun—highly recommended.
Using this riddle as a base, it could also be great to have the adult try solving riddles that the child creates next time.
Fun addition
The video features trains and bullet trains, making it the kind of video that would likely interest elementary school students, especially boys.
Even if at first they’re only interested in the trains, try not to force studying on them—be patient and wait.
They’ll surely come to enjoy learning math.
Rule-based puzzle
I think many elementary school students love solving quizzes, but if you’re going to tackle quizzes, choosing slightly more difficult ones is recommended because they stimulate the brain more.
The problems in this video are quizzes where you infer a pattern based on hints.
By relying on limited information and figuring out what the table is trying to represent, the answers will naturally become clear.
Also, with this type of quiz, the more you solve, the easier it becomes to find the underlying rules, so I recommend doing a lot of them.

A math quiz that tests 3D spatial recognition skills
It’s a problem where diagrams of a certain solid are shown from various angles—top, left, front, and so on—and you’re asked to find its volume.
It can be quite challenging because it tests your ability to visualize the solid in your head.
I’ve heard that people who are good at these kinds of problems also tend to be good with maps.
3 solid geometry area quizzes
This is an area quiz for elementary school students.
Kids can solve it, but there’s a trick, so I think it’ll be challenging even for adults.
Prepare a notebook by yourself, pause on the question page, and once you’ve solved it, read the answers and explanations—doing so should help improve your math skills.
