3 D shapes

The focus of the Unit 1 was on the properties of 2-dimensional shapes, location, and spatial relationships. This unit builds on these concepts, extending them to 3-dimensional shapes.

Free exploration of solid geometric objects over time is essential for developing spatial sense in kindergarten. It begins with play. The Block Center takes on increased importance in providing a setting for informal, but intentional, conversations about shapes and structures. Interacting with students at a Block Center and Shape Center affords an opportunity for asking questions and modeling mathematical language.

In this unit we will identify and describe shapes (squares, circles, triangles, rectangles, hexagons, 
cubes, cones, cylinders, and spheres).
Describe objects in the environment using names of shapes, and describe the relative positions of these
objects using terms such as above, below, beside, in front of, behind, and next to.
Correctly name shapes regardless of their orientations or overall size.
Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).

The Wild Cats have been exploring these 3 Dimensional shapes recently. We were trying to figure out which shapes can roll. We also put shapes together and counted sides, corners, vertices and edges. We have a lot of new mathematical vocabulary as we inquire into this unit.

We went around the school to see if we could identify these shapes in the environment. This shape hunt was a lot of fun.

Next we tried to build our very own shapes with modelling clay and tooth picks. This was a pretty challenging task...
