1, let the children review the points that are consistent with their hands and mouths.

3. Learn to count within 20 and learn how to write numbers.

Activities to be prepared

1, some magnets for tomatoes, watermelons and ducklings, and some digital magnets.

2. Children's books.

Activity process

1, draw a chart on the blackboard, put the physical tiles in the table, and let the children choose the corresponding digital tiles and put them in the back table.

2. Teachers can ask one child to come to the front, choose and paste the numbers of a physical tile according to the child's own wishes, then ask another child to count on the blackboard and paste the numbers on this tile, and ask other children to judge.

3. For the same kind of physical tiles, teachers can invite different children to the front for quantity selection and placement, which can generate more new topics and give children more opportunities.

4. Children's books. Guide the children to count the strawberries, biscuits, flowers and sweets in the box one by one, and let them say, "How many strawberries is a * * *?" Or some biscuits, some flowers, some sweets. Guide the children to write down the number of each item in the back box.

5. Teacher evaluation.

Teaching reflection:

Judging from children's feedback in class, children can count and write within 20, but there are some irregularities. The main problem is that six children wrote 6 backwards when writing 16: Yunna, Ningning, Xiaoyu, Fan Xiao, Chengyu and Zixuan. In addition, Zixuan wrote 16 as 6 1, 17 as 7 1 and so on. The children are still ambiguous about the left and right issues. Please ask the parents above to guide their children to strengthen the writing of exercise 6 at home.
