Student Target

“I can create composite shapes out of basic shapes and use basic shapes to create composite shapes”

CCR Focus Standards

Geometry - Level B

• 3.MD.7

  Relate area to the operations of multiplication and addition.

Supporting Standards

• 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.
  

• 3.G.2

  Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.
