Lesson

• Introduction
  • Students should be introduced to the concept that one dimension is a line, two dimensions gives an object area and shape.
  • 2-D objects can be recognized as shapes and drawn on paper.
  • 3-D objects are those that you can hold, and are those with which we are most familiar. Three dimensions give an object volume.
  • Dimensions can be described as length, width, and height. If an object has all three, it is 3-D, if it has two it is 2-D, and so on.
  • 3-D shapes are often formed by the putting together of other shapes.

• Practice
  PLEASE NOTE: The shapes are the same in both sets, though they vary in size and color.
  • Challenge your student to name the different shapes used to form each of the blocks (ex. The hexagonal prism has hexagons on top and bottom, and rectangles for the sides.)
  • Challenge your student(s) to a scavenger hunt. Give each player a piece of paper and a writing utensil. Have each go around the house/yard/room and label the shapes he/she finds, where, and whether it is two or three-dimensional. (ex. The sofa cushions are rectangular prisms, 3-D)
