# Math Topics K 5 Understanding Shape

Grade 1 (1.G.A.1) Reason with shapes and their attributes.
Ages 5 - 6

## 2D-Shapes

MEETS 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.

Grade 1 (1.G.A.2) Reason with shapes and their attributes.
Ages 8 - 9

## Nets

SUPPORTS 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.

Grade 2 (2.G.A.1) Reason with shapes and their attributes.
Ages 6 - 7

MEETS 2.G.A.1: 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.

Ages 6 - 7

## Big Shape Show

SUPPORTS 3.G.A.1: Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.

Grade 4 (4.G.A.1) Draw and identify lines and angles, and classify shapes by properties of their lines and angles.
Ages 9 - 10

## Geometry Drawing

SUPPORTS 4.G.A.1: Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
