Last semester, in grade one, we learned three-dimensional graphics, such as cubes, cuboids and spheres. This semester, we studied plane figures, such as squares, rectangles, parallelograms, triangles and circles. In order to better distinguish between plane graphics and three-dimensional graphics, let's make it!

First, production

1, three-dimensional graphics: use packaging boxes, medicine boxes, gift boxes, etc. Plaster is also used to encourage hands-on production.

2, graphic: DIY.

Second, playfulness.

1, make a favorite three-dimensional combination diagram, such as making a small house, a robot and a favorite animal.

2. Decorate the plane graphics on the three-dimensional combination graphics.
