We support teaching-learning related to stacking trees and three-dimensional figures (various pillars and horns) in the elementary school math department.

1. Stacking trees in various shapes,
2. Find out how many trees are stacked,
3. Stacking in the same shape,
4. It contains the shape and development of the prism and pyramid.

Teachers can use it in class or students can use it personally. There are similar applications, but this application takes into account the teaching and learning of the Department of Mathematics, makes it possible to apply in more various situations, and includes a part that allows you to learn a variety of three-dimensional figures.
