When judging before and after, judge for yourself. The direction your eyes see, that is, the direction you face, is the front, and the direction your back is facing, that is, the direction your back is facing, is the back.

In the first grade, you should distinguish whether the things on the table are left or right. First of all, you should let your child know where your left hand is and where your right hand is. Then when facing the things on the table, the things on his left hand side are the left side, and the things on his right hand side are the right side. If his right hand is still confused, you can tell him that his right hand is the hand that writes and holds chopsticks, and the other side is his left hand.
