Lesson Purpose

To inform students that, in math, there are often many ways to get to the same end (via using different smaller shapes to create a larger composite)

Lesson Objectives

At the end of this lesson, students will be able to use pattern blocks and shapes to create composite shapes.

Student Target

“I can create composite shapes.”

CCR Focus Standards

Geometry - Level A

• 1.G.2

  Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.

Supporting Standards

• 1.OA.6

  Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
