construction of 3D objects
Elaboration
- identifying 3D objects according to the 2D shapes of the faces and the number of edges and vertices (e.g., construction of nets, skeletons)
- describing the attributes of 3D objects (e.g., faces, edges, vertices)
- identifying 3D objects by their mathematical terms (e.g., sphere, cube, prism, cone, cylinder)
- comparing 3D objects (e.g., How are rectangular prisms and cubes the same or different?)
- understanding the preservation of shape (e.g., the orientation of a shape will not change its properties)
- jingle dress bells, bentwood box, birch bark baskets, pithouses
