Satisfyingly Tricky: Challenging Quizzes for Elementary School Students! (1–10)
Elementary school entrance exam question that even adults can’t solve

They say this is an entrance exam question for elementary school.
The fact that there are people who can even come up with problems like this makes me realize just how many different kinds of people there are in the world.
What kind of mind does it take to think up such questions, or to find them fun? For me, that will forever be a mystery (lol).
Since it’s people like that who develop the convenient things we use in the world, maybe the best thing is for each of us to do what we’re good at.
Arithmetic Olympiad problem: “How many horse mackerel are there?”

The Math Olympiad is popular even among elementary school students.
The problems are certainly challenging, but solving them feels refreshing and gives a sense of accomplishment.
This particular problem should be solvable with the math knowledge of a third grader, yet even current University of Tokyo students have only a 19% correct answer rate—it’s a problem that tests mathematical intuition.
It seems like good brain training not only for doing straightforward calculations but also for thinking about the best approach to reach the correct answer, so it could be fun to tackle it as a family.
A riddle that seems easy but is difficult

Problems that are too difficult aren’t suitable for everyone to enjoy together, but a quiz like this is approachable, so I think everyone can have fun solving it with lots of lively chatter.
It may seem easy, but once you get tripped up, it can become confusing, and some people might not be able to solve it within the time limit.
Also, once you know the answer, you can keep it as your own little trick and show it off when playing with classmates or friends, so you could say it’s one of those handy quizzes that’s useful to know.
Math problem: “What is Lisa’s score?”

This problem was previously used as an entrance exam question for the junior high division of Kumon Kokusai Gakuen.
It asks you to infer the remaining student’s score based on the results of the others.
Similar problems using this approach appear in various entrance exams, so why not try it as practice for this pattern? Once you solve one, you start to get the method.
It also makes a good brain-training exercise for adults.
It sounds fun to try solving it together with an elementary school child and the whole family.
A riddle that tests your flash of inspiration! Question 39

Problems that require using a flash of insight to produce an answer instantly—rather than thinking things through slowly—are hard because they make you use different parts of your brain that you don’t usually use.
Here is a set of problems designed to develop that kind of insight.
Using only a few hints to derive the answer makes this type of puzzle fun, as it feels like you’re gradually unraveling it.
As you solve more of these, you’ll get faster at them, so I recommend trying many.
[Correct Answer Rate 0%] An Elementary School 5th-Grade Problem That’s Far Too Difficult
![[Correct Answer Rate 0%] An Elementary School 5th-Grade Problem That’s Far Too Difficult](https://i.ytimg.com/vi/jVjfBCTptHM/sddefault.jpg)
The Junior Math Olympiad is a competition where elementary school students in 5th grade and below compete in arithmetic.
The problems introduced here are easy to solve if you use high school knowledge, but the challenge is to solve them using only what a 5th grader would know.
The correct answer rate is an astonishing 0 percent—an extremely difficult problem.
To tackle this kind of question, you need to approach it from various angles, and just thinking through those approaches is a great mental workout.
When you finally solve it cleanly, you’ll likely find yourself captivated by arithmetic.
Quiz Showdown

This is a video where elementary school students and adults actually compete in a quiz showdown.
I don’t think there are many videos like this being posted.
It’s a speed battle, so it’s fun to watch.
Unlike TV, there’s probably no staging, so they’re really going all out.
Rather than a paper test, seeing how things play out in a real, live contest is the most compelling and entertaining part.
A problem that children can solve quickly but adults are likely to get wrong

This video is a collection of high-difficulty 10-times quiz questions.
They’re the kind of problems that will trip you up unless you stop and think a bit.
These are guaranteed to be a hit with elementary school kids.
I love this kind of question myself.
I wonder how many types of 10-times quizzes there are—maybe even infinitely many.
This video made me want a book that compiles 10-times quizzes.
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.
Three maze problems in total

This is a maze-solving type of puzzle.
Once you cross a bridge, it breaks, but you’re allowed to pass through the same island as many times as you like.
Islands with only two bridges will lose both bridges just by passing through, so the key is to make good use of islands that have many bridges.
That said, there are also bridges you won’t use, so be careful.
It might be helpful to mark impossible paths with an X.
Trying to solve the problem from various angles seems like it could activate parts of your brain you don’t normally use.
