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.
- Children will do this activity on the carpet initially and then individually either at their desks or on the carpet.
- Children should have experience playing with interlocking cubes.
- Interlocking cubes
- 3 Views Picture (download)
- Facilitate a discussion to prompt students to think about how to transform a 2-D drawing into a 3-D structure.
- Provide students with interlocking cubes (about 20) and a 3 Views Picture (attached).
- Ask students to imagine if they were a bird flying over and round a building: how they would see the building different views?
- Then, ask students to look at the “3 Views Picture.”
- Ask students to make a building that has the same top view, front view, and side view as the “3 Views Picture.”
- Encourage students to compare their structures with each other to verify that their building matches the “3 Views Picture.”
- What directional or positional language does the child use? (e.g. over, under, left, right)
- Do they use the proper names of 2-D and 3-D shapes?
- Can they articulate how they interpreted the 2-D pictures and applied that to the 3-D structures?
