As you can see from the article, you are a very responsible primary school teacher. The performance of these two children is normal and cute, which is a common problem of our first-grade children when they are ignorant. I think you can:

1. Use some teaching AIDS to help guide them, such as color sticks, vertical counters and other teaching AIDS;

2. You can also find some shapes of food to reward them and stimulate their interest in learning;

You need to talk to your parents and ask them to take care of your children, especially those who can't count. Parents need more private counseling to cooperate with your work.
