[Satisfying When Solved] Challenging Quizzes Recommended for Elementary School Students!

For all elementary school students who love quizzes, we’re introducing a whole bunch of tough questions this time!

If regular quizzes are a breeze for you and you’re looking for a new challenge, give these a try.

We’ve gathered quizzes ranging from Math Olympiad problems and entrance exam questions from competitive junior high schools to puzzle-like brainteasers and tricky riddles.

With every question, once you see the answer you’ll think, “Oh, that’s what it was!”—and maybe feel a bit frustrated—but we believe it’s a great way to discover how fun learning can be.

If you find a quiz you like, we also recommend sharing it with everyone at school.

[Satisfying When You Get It] Challenging Riddles Recommended for Elementary School Students! (31–40)

Matchstick puzzle: Move 2 sticks to change the direction of the goldfish.

See the answer

Move the two sticks at the bottom right to make the goldfish face upward.

When we see the phrase “change direction,” we tend to assume it means “turn 180 degrees”—right to left, up to down, and so on. If someone said “either up or down is fine” for this problem, it would click right away, wouldn’t it? Still, it’s kind of curious that with just this many matchsticks, the figure can look like a goldfish.

[Math Quiz] 5-Yen Coin Savings

[Arithmetic Quiz] Looks easy but a bit tricky! Brain training and IQ boost with math problems! “5-Yen Coin Savings”
[Math Quiz] 5-Yen Coin Savings

This is a 5-yen coin saving quiz that’s also effective as brain training.

In this quiz, there’s a boy who saves 5 yen every day.

Since his piggy bank was small, he would exchange coins as follows: when he had two 5-yen coins, he exchanged them for a 10-yen coin; when he had five 10-yen coins, he exchanged them for a 50-yen coin; when he had two 50-yen coins, he exchanged them for a 100-yen coin; and when he had five 100-yen coins, he exchanged them for a 500-yen coin.

Based on these conditions, let’s determine the coin amounts at specific counts.

The trick is to think in terms of the smallest possible denominations.

This is a type of problem where you find the answer through associations.

Elementary school students love questions like these.

They learn lots of facts, enjoy showing what they know, and come to discover the fun of studying—those children, I think, tend to achieve excellent results.

I believe these kinds of problems are very effective for developing the ability to have flashes of insight.

When trying to answer this question, wouldn’t most people say, “You’re supposed to answer Wednesday, but the trick is that the answer is Thursday!”? That’s what common sense suggests, right? In fact, if a small child answered that way, I’d be tempted to mark it correct—they’re being clever.

However, the answer is actually neither Wednesday nor Thursday.

The key to finding the answer is to focus on the word “asatte” in the problem statement.

Look closely: while “today” and “tomorrow” are written in kanji, “asatte” is written in hiragana… What does that imply?

[Arithmetic Olympiad Super-Challenge] What is the perimeter of the rectangle?

At first glance, the perimeter here looks difficult to figure out, but since the light green shape inside is a square, you can easily find the answer by setting up an equation: let the side length of the square be ○, let the part obtained by subtracting the square’s side from 12 cm be □, and the part obtained by subtracting the square’s side from 9 cm be △.

For problems that seem hard, it’s a good idea to try replacing numbers with symbols and see if you can simplify your approach.
