2.GSR.7Shapes and Partitioning

Expectations

• 2.GSR.7.1

  Describe, compare and sort 2-D shapes including polygons, triangles, quadrilaterals, pentagons, hexagons, and 3-D shapes including rectangular prisms and cones, given a set of attributes.

• 2.GSR.7.2

  Identify at least one line of symmetry in everyday objects to describe each object as a whole.

• 2.GSR.7.3

  Partition circles and rectangles into two, three, or four equal shares. Identify and describe equal-sized parts of the whole using fractional names (“halves,” “thirds,” “fourths”, “half of,” “third of,” “quarter of,” etc.).

• 2.GSR.7.4

  Recognize that equal shares of identical wholes may be different shapes within the same whole.
