By the end of Grade 2/3 students should be able to:
- identify,describe and name various three- dimensional figures (i.e., cubes, prisms, pyramids) and
sort and classify them by their geometric properties (i.e., number and shape of faces), using concrete materials (e.g.,“I separated the figures that have square faces from the ones that don’t.”);
– create models and skeletons of prisms and pyramids, using concrete materials (e.g. connection math set, pipecleaners and straws or sticks and modelling clay) and construct prisms/pyramids from paper nets noting the number and shape of faces, number of edges and number of verticies.
We have had a lot of fun working on these curriculum expectations in class.- *We wrote clues to describe the 3D solids.
- *We sorted models of 3D solids according to many different sorting rules and then showed this thinking using paper pictures.
- *We practiced comparing different 3D solids by finding the similarities and differences in number/shape of faces, edges and vertices and recording our thinking in words.
- The proof is in the pictures! Enjoy!
