Can you solve it if you’re flexible-minded? Brain training with a math quiz
“I’m not good at math…” Don’t you hear that a lot? In fact, there are plenty of math quizzes you can enjoy like puzzles and games.
From addition and subtraction to 3D shapes and unit conversions, a full lineup of fun problems will tickle your brain.
You can take on calculations while adventuring through Mario’s world, or fill in numbers like a crossword puzzle…
The world of math is surprisingly fun! Try challenging yourself—together with your child, or even among adults.
Can you solve it if you’re quick-witted? Brain training with arithmetic quizzes (1–10)
What number goes in the question mark?
If you’re not good at arithmetic and don’t even want to look at numbers, how about getting used to them with riddle-like puzzles? For example, consider this sequence: 11×11=4, 22×22=16, 33×33=36—at first glance, the operations and answers don’t seem to make sense.
At the end, you have 55×55=? and you’re asked to determine what should go in the question mark based on the rule behind the previous expressions.
The hint is to break the numbers in each expression into separate parts.
If you get that flash of insight and find the answer, your discomfort with numbers should start to fade! Give it a try.
A math quiz with answers that can vary
What’s the answer to “9×9÷9×9”? The result changes depending on the order of operations.
How do you think it should be calculated correctly? Elementary school kids who are learning this in real time might come up with the answer right away.
But adults might find themselves thinking, “Huh? Where do I start the calculation?” Should you go from left to right, or do the multiplications first? Please think it through and try to find the answer.
Problems that look simple like this can really make you overthink, can’t they?
Telling Time Quiz
To be able to quickly say what time it is when you look at a clock, let’s learn how to read clocks properly using a quiz format! If you have a toy clock with movable hour and minute hands, try using it.
First, keep the minute hand fixed at the 12 and move only the hour hand, answering what hour it shows.
Once you get used to that, start moving the minute hand as well so you can answer the exact time, down to the minutes.
Also, try some applied quizzes like: “What time will it be ○ minutes from now?” and “What time was it ○ minutes ago?”
Only 3% of adults get it right! A 4th grade elementary school math problem
https://www.tiktok.com/@mayeexuw6q1/video/7472027193460133128When you’re suddenly given just this information—“A pencil and a notebook together cost 100 yen, and the pencil is 40 yen cheaper than the notebook”—it’s not uncommon to panic and answer that the pencil costs 60 yen.
But that’s incorrect.
Saying “40 yen cheaper” doesn’t mean the notebook costs 40 yen.
You need to find prices where the difference between the pencil and the notebook is 40 yen.
With problems that have a bit of a trick like this, it’s important not to blurt out an answer right away, but to pause for a moment.
Try shifting your way of thinking, and you’ll start to see the numbers differently.
Volume Unit Quiz
When expressing the volume of water, we use units such as mL, dL, and L.
If your child has had a math lesson on measuring liquid volume, have them actually pour water into a measuring cup and answer, in a quiz-like format, how much is inside.
If you have several cups with markings, ask them to add the amounts—how much do you get when you combine this cup and that cup? Also, these units change as the quantity increases.
Along with the amount of water, study how the units convert—for example, 10 dL becomes 1 L, and 100 mL becomes 1 dL.
Grade Check Quiz
Not just in arithmetic—every subject gets harder with each grade.
Let’s check what level of arithmetic problems you can solve using grade-appropriate quizzes.
In 1st grade, you’ll see addition and subtraction with one- to two-digit numbers; in 2nd grade, calculations with two or more digits; in 3rd grade, multiplication and division with remainders appear; and in 4th grade, you start calculating with decimals.
In 5th grade, decimal calculations become more advanced, and in 6th grade, fractions are introduced.
Even if you think you understand decimals and fractions, it’s easy to have misconceptions or make calculation errors, so keep practicing with a variety of problems to build familiarity!
Use symbols to make four numbers equal 10.
Insert one of the symbols +, −, ×, or ÷ between four randomly arranged numbers to make the final result 10—this makes a perfect brain-training activity! If you use parentheses, you can freely change the order of operations, so children who have learned parentheses should actively incorporate them.
Also remember that multiplication and division are performed before addition and subtraction, so keep that in mind as you complete your expressions.
Once you get used to it, it might be fun for parents and friends to take turns making problems for each other!
Math quiz while memorizing
This is a calculation quiz where you solve problems across three difficulty levels: easy, normal, and hard.
You answer addition, subtraction, multiplication, and division questions within a time limit.
The fun twist is that you first memorize a 5-digit number.
While making sure you don’t forget that number, keep solving the problems.
If you can recall the memorized number at the end, you’re good! The number is presented as a three-choice multiple choice, so it’s on the easier side, but many people may still forget it by accident.
Give it a try!
Rule-Filling Quiz
The problem is: “16→23→28→38→49→62→70→?”.
Think of the number that goes in the question mark and give your answer.
To figure it out, you need to identify the rule from these seven numbers that increase little by little.
While they all increase, the increments vary: sometimes it goes up by 7, other times only by 5.
However, if you look closely, there’s a certain rule in how it increases…
The hint is to consider the ones and tens digits separately.
Now, can you uncover the rule?
Which is the correct answer? A two-choice quiz on calculations
This is a math quiz with four levels: Easy, Normal, Advanced, and Master.
It features calculation problems in addition, subtraction, and multiplication.
Each question has two choices for the answer, so pick one within the time limit.
As the level increases, the numbers get larger, but it’s not too difficult.
However, because the answer is revealed after a 3-count, the time to think is short.
Stay calm and calculate carefully.
Elementary school students can have fun, and adults are encouraged to aim for a perfect score.
