So young, don't give him too much pressure, give him more counseling. For such a young child, connect mathematics with life situations and learn in life. When eating cookies and sweets, give four first, then four, and let the children count. Ask the child how much to eat first, if it is not enough, then ask the child how much to eat. When I was a child, I didn't lay a good foundation in mathematics, and I will suffer from further study.
