As learning progresses they perform tessellations on a isometric grid.

**Differentiated Learning Objectives**

- All students should be able to tessellate with triangles and quadrilaterals.
- Most students should be able to understand how to tessellate a shape.
- Some students should be able to understand why a shape does not tessellate.
