K.7 Solid Shapes All Around Us

Unit Goals

  • Students identify, describe, analyze, compare, and compose two- and three- dimensional shapes. Counting, addition, and subtraction are revisited in the geometric contexts.

Section A Goals

  • Compose shapes from smaller shapes.
  • Count and compare numbers, and solve story problems involving shapes.

Section B Goals

  • Compare weight and capacity of objects.
  • Compose shapes from smaller shapes.
  • Describe and compare three-dimensional shapes.
