The programming environments" for children" allow not only for children to learn programming, but also for teachers to develop teaching materials of various subjects. For example, Squeak is one of them. The developed teaching materials can purvey the simulation environments in the classroom. It will be necessary to study the effective use of the materials on each teaching content. Here, we concentrate on function and its graph that should be learned from arithmetic in primary school to mathematics in high school. We develop the prototype of the material for drawing graphs of functions and translating graphs by Squeak, and discuss the way to use it. As a result, we found it would make children understanding concrete by using it after drawing graphs by their hands, and deep when it is used repeatedly at many school terms. It, furthermore, would be modified and/or extended to adjust other contents that should be presented by graph. We also found that the basic scripts in the material can be constructed simply enough that children be able to read and extend those by themselves. This fact will possibly lead to the consequence of the growth of their interest in arithmetic, mathematics, and/or other subjects.

The purpose of this study was to examine statistically the relationship between the shooting position and the place of getting rebounds. For the object, We selected randomly 16 games in the men's top league of university. For the method, We videotaped the games. We divided the court into 5 areas by the angles of the shot and 6 areas by the length of the shot and tally up the data of shooting position and the place of getting rebounds. We analyzed the data by Pearson's correlation analysis, and examined with thepercentage of the rebounds. The results are the following.1)For all the angles of the shot, as the length of the shot gets longer, the distance of the rebound becomes longer.2)For 3 point shots, as the shooting angle gets closer to the left corner, the length of rebound becomes longer.3)For the shot over 3.75 meters, the angle of rebound is same as the angle shot on the help-side.4)As the length of the shot gets longer at the right corner, the angle of the rebound becomes closer to help-side corner. From the above results, it revealed statistically the relationship between the shooting position and the place of getting rebounds. In conclusion, it was suggested that when the team control the place of getting rebounds, it was related to getting more rebounds and the possibility leading to ascendancy in the game.
