Primary: Geometry and Spatial Sense
- Compare two-dimensional shapes and three-dimensional figures and sort them by their geometric properties.
- Compose and decompose two-dimensional shapes and three-dimensional figures.
Junior: Geometry and Spatial Sense
- Identify and classify two-dimensional shapes by side and angle properties, and compare and sort three-dimensional figures.
- Sketch three-dimensional figures, and construct three-dimensional figures from drawings.
- Students sit on the carpet then move to their desks.
- Students should have experience playing with interlocking cubes.
- This is an extension of the “Build a structure from 3 different views” lesson.
- Interlocking cubes
- Grid paper
- Review with students how interlocking cubes can make different shapes.
- Facilitate a discussion to prompt students to think about how to transform a 2-D drawing into a 3-D structure.
- Construct an interlocking cube structure. This structure can be made from 4 cubes to 20 cubes. It can be any shape and have different colours.
- Place the interlocking-cube structure on a fixed surface.
- Provide students with small grid paper and coloured pencils.
- Ask students to use the grid paper to make 3 drawings that represent the different views (i.e. top view, front view, side view).
- Ask students to compare their top views, side views and front views of the structure.
- Ask students to exchange drawings and verify them by discussing the different views.
- What directional language does the student use (e.g. over, under, left, right).
- Do they use proper names of 2D and 3D shapes?
- Can they articulate how they interpreted the 3D structures and applied that to the 2D pictures?
- Students can make their own structure and challenge a partner to draw it.
