- 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.

- 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
- Three Views Picture

- 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 the Three Views Picture.

Ask students to imagine if they were a bird flying over and round a building. How would they describe the structure and its different views? - Then, ask students to look at Three Views Picture
- Ask students to make a building that has the same top view, front view, and side view as Three Views Picture
- Encourage students to compare their structures with each other to verify that their structures match the examples in Three 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?
