Cluster:
Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres).

Standard:
Correctly name shapes regardless of their orientations or overall size.

Cluster:
Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres).

Standard:
Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).

Cluster:
Analyze, compare, create, and compose shapes.

Standard:
Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/“corners”) and other attributes (e.g., having sides of equal length).

Cluster:
Analyze, compare, create, and compose shapes.

Standard:
Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.

Cluster:
Analyze, compare, create, and compose shapes.

Standard:
Compose simple shapes to form larger shapes. For example, “Can you join these two triangles with full sides touching to make a rectangle?”

Cluster:
Reason with shapes and their attributes.

Standard:
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.

Cluster:
Reason with shapes and their attributes.

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.

Footnote:
Students do not need to learn formal names such as “right rectangular prism.”

Cluster:
Reason with shapes and their attributes.

Standard:
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.

Cluster:
Reason with shapes and their attributes.

Standard:
Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

Footnote:
Sizes are compared directly or visually, not compared by measuring.

Cluster:
Reason with shapes and their attributes.

Standard:
Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
