The first stage: identification and counting

This stage is the basic stage of children's mathematics enlightenment. Children before the age of 2 generally count and count at this stage. Some children may know numbers first and then learn to count; Some children may learn to count before they know numbers. There is no order of recognition and number, only related to children's hobbies and habits.

1. Acknowledge

Numbering ability is related to children's memory. It means that the child knows this number. This skill means that children know the number 1- 10.

count

Children's self-study number 1- 10. This skill means that children know the "quantity" of 1- 10. Here, the teaching assistant recommends that parents can prepare some small and easy-to-master items as counting materials, and recommend: square building blocks, coins, candy, etc. 3 understand the total. After understanding the identification and counting, children can immediately answer the correct number when they ask how many "a * * *". At the beginning, parents can help children understand the concept of "total" with their children's points.

The second stage: quantity matching

When children can find the correct number according to the number of counted items, they can match the number with the number, that is, arrange the corresponding number of items according to the number.

1. Take things by numbers

That is, find the corresponding number of items according to the numbers.

Step 2 match things with numbers

That is, according to the number of items counted, find the correct number.

The third stage: equation matching

The equation here does not refer to the equation of addition and subtraction, but the comparison, division and combination between numbers.

1. Split and merge

After understanding the relationship between number and quantity, children usually realize that quantity can be "split" and "combined" Ps: in the cognitive manual of cube number, cube eating apples, addition puzzles, splitting games, addition game machines and little monster reasoning all involve the splitting and combination of numbers.

2. judge >,

After entering the stage of quantity matching, children will begin to know the size of numbers. At this time, you should give your child some exercises to judge the amount.

After the completion of these three stages, the child has mastered the concept of numbers within 10 and the addition and subtraction operations. On this basis, it is easy to understand by learning the addition and subtraction of numbers within 20 and 100.
