To understand the concept of mathematics, zero can be the starting point, weight and measurement of the competition. Zero can also be used as a demarcation point. On the thermometer, 0 is the dividing point between water freezing and melting. Zero is not just nothing, it has many functions. From 1 to 9, children usually find it very simple. However, when the rounded number is 10, many children can't turn the corner.
3. Use gadgets to exercise mathematical thinking. I borrowed this set of first-grade mathematics textbooks and found that a large number of visual tools such as number axes and number tables were used in the book, which made the number arrangement appear regular, which was very consistent with the cognitive laws of lower-grade children. The number axis can let children know clearly how the numbers increase, and know the size and distance relationship between the numbers.
