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.
