No more difficult math books!
Have fun learning units and measurements while having fun!

● Basic concepts of elementary mathematics - learn units and measurements
This book covers measurements and units that are important in elementary mathematics.
Measurement is the measurement of the size or quantity of something.
It's about finding out length, weight, volume, time, temperature, etc.
You will learn the basic concepts of measurement, including units such as cm, mm, kg, L, and ℃.
You will also learn how to use measuring tools such as rulers, scales, and thermometers.
Children learn to read the clock, which is difficult for them, and also learn the relationship between 1 second, 1 minute, and 1 hour.


● Enjoy math as if you were playing by unfolding, lifting, and pulling!
Math is hard? Unfold the pop-up, open the flap, and spin the wheel.
Learn to read the clock by turning the turntable, check the temperature by lifting the flap, and measure the length of objects with the ruler in the book.
Math feels like play.


● Reinforce what you've learned with a short quiz
There are short quizzes for each topic, and the answers to the quizzes are on the flap.
Let's solidify what we've learned by lifting, turning, and opening the flap.
By looking at the pictures in the flap, you can understand in detail even the difficult and easy-to-get-wrong contents.


● Connecting life and math
The questions and quizzes in this book are fun.
Because it mathematically represents problems that we commonly encounter in our lives.
You can figure out which is wider, the window or the closet in your room, by eye or by measuring it with your hand.
You can measure without having to show the exact number.
To know the temperature of the room and the temperature of the fish tank, you can look at a thermometer.
It's okay if there are no numbers.
Just look at the height of the mercury column in the thermometer.
Ultimately, you will come to realize that units and measurements are necessary to make our lives easier.
Children can feel familiar and necessary with units, measurements, and even mathematics.
