3D Shapes in Geometry

The final component of Geometry and Spatial Sense this year is 3 dimensional shapes.  In Grade 3, students focus on prisms and pyramids.  Here are the expectations that we are covering in class this week:

• identify and describe the two-dimensional shapes that can be found in a three-dimensional figure

• describe and name prisms and pyramids by the shape of their base (e.g., rectangular prism, square-based pyramid)

• compare and sort prisms and pyramids by geometric properties (i.e., number and shape of faces, number of edges, number of vertices), using concrete materials

• construct rectangular prisms and describe geometric properties of the prisms
