Standard

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.

Student Language:

• "I can create two dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles and quarter-circles)."
• "I can create three dimensional shapes (cubes, right rectangular prisms, right circular cones and right circular cylinders)."
• "I can use two- and three-dimensional shapes to create new shapes."
