- 1.G.A.1 Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size) ; build and draw shapes to possess defining attributes.
- 1.G.A.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.
^{1} - 1.G.A.3 Partition circles and rectangles into two and four equal shares, describe the shares using the words
*halves*,*fourths*, and*quarters*, and use the phrases*half of*,*fourth of*, and*quarter of*. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.

^{1} Students do not need to learn formal names such as “right rectangular prism.”
