Does your child like to play? That's good. Explain that your child has the premise of learning calculation and mathematics. You can play flying chess for your child. This is very useful. Let children learn to walk step by step and know the main points. This can cultivate his counting ability. Then let him learn to count with his eyes when he is proficient in playing, or take two steps in two steps. Finally, let the children master the rules of flying chess. Every four squares are the same color. If you are proficient in flying when you are a child, then your child's bright and sharp numbers will be strong and playing cards can be used. Play the game of ten, find the tortoise version, 9 and 1, 2 and 8, 3 and 7, 4 and 6, 5 and 5. You can ask your child to count the number of patterns on the card, which will make it easier for him to understand. Learning to arrange and arrange is also the basis of learning mathematics.

My self-taught children are very good at playing chess and cards, and the exam of 100 is also very simple. Basically, they can do well in the exam without reviewing, so playing before the exam is better for their study.

In fact, what you said is counting with your fingers. I have introduced this to many children before, which is really annoying. As long as you are patient, I finally introduced this shortcoming.
