Find something easy to count in daily life: buttons on shirts; Oranges on supermarket shelves; Steps when going upstairs ... start with a relatively small number (no more than five) and gradually increase the difficulty, so as to ensure that your child will continue to accept challenges.

2. Change the arrangement.

Find some coins and let the children count as many as possible. First, let him count coins; Then, you change the arrangement of coins, for example, from a column to a circle, and then ask the children to count them again. If he is surprised to get the same number, he will change the arrangement of coins once and let him continue counting until the child answers automatically instead of counting. At this time, the child has understood the invariance of numbers.

Step 3 find something to match

If the child has some difficulties in one-to-one correspondence, you might as well play a game of matching items with him to help him master this skill. The tools you need can be spoons and bowls, cups and plates, cocks and hens. In the course of the game, you keep pairing your child-so that his understanding of "one-to-one correspondence" can be deepened.

4. Play a board game including counting.

Some simple board games, such as candy paradise, are very suitable to help children master the usage of dice and related counting rules when playing. Other more complex games may involve more numbers, such as poker. I suggest that parents use simple games in the early stage of training to avoid discouraging children's enthusiasm and increase the difficulty of games after children master certain math skills.

5. Know the shape of your home

Show your children the basic geometric shapes around your home: square light switch, round bowl, triangular road sign ... Let your children talk about the similarities and differences of these geometric shapes, which can help them write down the characteristics of each shape and distinguish them effectively.

Step 6 discuss the pictures in the book

When reading picture books with children, guide children to describe the pictures they see in spatial language. For example, "Where is the moon? Is it above or below the tree? " Or "Is it bigger than a hippo or a monkey? Is the hippo small or the monkey small? "

7. Draw a map for your home

Maps can help children use space language more at home. When a child is drawing a map, parents can constantly ask him about the relative positions and sizes of furniture, windows, picnics, gardens and bushes.
