When my son was over 2 years old, I began to buy him toys about numbers: digital puzzles, toy clocks, digital building blocks and a small blackboard with the number 10 written on it. These toys, let the son know 0 ~ 9, together is a wonderful game. My son had such a good time that he could count to hundreds before he knew it.

You can also love numbers through digital picture books.

As my son grew up, I began to let him read children's books. There are numbers in many children's books, such as Numbers in the series "Little Mouse Books Without Words", in which a cute little mouse is unwilling to be lonely, biting out a number of holes bit by bit on the snow-white page, forming different numbers of little mice. In My First Book, there are also numbers. By reading these books about numbers, my son is more interested in numbers. After I was 3 years old, I began to read books about the development of left and right brains to my son. Many of them are about the application of numbers, which are used in middle schools and schools. My son will unconsciously do simple addition and subtraction problems. He began to like being tested, and I often gave him a few simple arithmetic problems at will, and my son could work them out slowly.

You can also compare children's songs with physical objects. For example, 1 is as thin and long as a pencil, 2 floats on the water like a duckling, 3 listens to the sound like an ear, 4 shakes like a flag with the wind, 5 weighs something like a scale hook, 6 grins like a bean sprout, 7 mows the grass like a sickle, 8 twists, 9 holds rice like a spoon, and 0 makes a cake like an egg, so that you can easily identify the numbers by comparing an actual thing with a digital card.
