In math we have been learning about 2D and 3D shape attributes. Yesterday our learning target in math was, "I can identify flat surfaces on 3D objects." Here is a list of the 3D shapes we discussed and the number of flat surfaces they have:
*Rectangular Prism- 6 flat surfaces
*Cube- 6 equal sized flat surfaces
*Triangular Prism- 4 flat surfaces
*Cylinder- 2 flat surfaces
*Cone- 1 flat surface
*Sphere- 0 flat surfaces
Today in math our learning target was, "I can identify 3D shapes that stack and explain why." Today each table group was handed several 3D shapes and were asked to build any type of tower they choose. After a few minutes of exploration, we discovered that only flat surfaces have the ability to stack. Curved surfaces would roll away.
In kindergarten, students were asked to identify 2D and 3D shapes. In first grade, students are expected to explain why a shape is a certain shape. They explain using vocabulary terms such as flat surface, edge, and vertex.
The first graders have been excelling in our 2D and 3D shape unit. Below you will find pictures of the groups with their final 3D shape tower.
