Unit 5, Lesson 4

Create composite shapes from two-dimensional shapes.

EngageNY 60 min(s)Support for English Language Learners

In this lesson, students create composite shapes (hexagons, rectangles, and trapezoids) from triangles, squares, and rectangles. They recognize that the same composite shape (whole) can be made from a variety of shapes (parts). For example, a hexagon might be made by composing six triangles or two trapezoids or one trapezoid and three triangles. Students also use square tiles to see that a large rectangle can have many combinations of smaller rectangles within it.
