| Research Abstract |
The purpose of the study is to develop the teaching material of meaningful "mathematical activity" for geometry education in elementary school. So, we examined the "meaningful mathematical activity" in elementary school, and we made systematic teaching materials of geometry education in elementary school. Actually, we made some teaching materials based on the result of previous studies. Moreover, we investigated 300 children in public elementary school, and we investigated the children's cognition for "proof" by investigations of making a problem expressed in words for them. In addition, we investigated the children's cognition for "transformation" by investigations of drawing a cube for them. Then, we made teaching materials of "proof" and "transformation" including "meaningful mathematical activity" for each stage. We verified a part of them by teaching practice etc. As the result, we achieved a positive result that the contents were validity for children.
