In the first grade, when the teacher taught us, there seemed to be no arrangement. At first, it was nothing to go home and do homework. It will be available in a few days. For example, copy the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0 for about ten times each, or you can work out several intersections yourself.

Classroom assignments, some formulas below can't be written, so write them in the classroom exercise book. That's what we used to do. By the way, don't be too hard on children.
