2.G.A. Reason with shapes and their attributes.

    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.Sizes are compared directly or visually, not compared by measuring. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

    2.G.A.3. Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
