In the elementary classroom, we are confronted with a six-year-old child whose interests are completely different from those of the child in the 3 - 6 classroom. The 3 - 6 year-old child is attracted by a limited environment: that of the family and the 3 - 6 classroom. The six-year-old is attracted by the larger environment. The teacher in the elementary classroom is often in the position of teaching the child to read, write, and calculate, before it is possible to open to the child the wonders of the world.
