Geometry (G) Reason with shapes and their attributes. CCSS.MATH.CONTENT.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. CCSS.MATH.CONTENT.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 CCSS.MATH.CONTENT.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.
