The first-level position cognition unit should establish three position relationships: up and down, left and right, and front and back. Different reference objects have different descriptions of the positional relationship. The positional relationship needs empathy. The method of judging the relationship between up and down positions: first determine the reference object, and then determine whether the described object is above or below the reference object. The method of judging the relationship between front and back positions is based on the reference object, with the direction facing the reference object as the front and the direction facing the back as the back. The left hand is on the right and the right hand is on the right.

Integrating mathematics knowledge into life, into interesting mathematics activities and games, and learning mathematics in specific scenes in lower grades can not only enhance children's enthusiasm for participation, but also better understand the knowledge in the classroom. The positional relationship is relative and is determined by the reference object or observation point. When determining the left and right, the observer's left and right are generally taken as the standard, but it is still necessary to classify and discuss according to the attributes of the observed object.
