Lesson

• Introduction
  • Define CIRCLE - a closed, curved line with all points equal distant from the center.
  • Define SQUARE - a closed figure with four equal length sides and right (or equal) angles.
  • Define RECTANGLE - a closed figure with four sides and right (or equal) angles
  • Define TRIANGLE - a closed three-sided figure
  • Define HEXAGON - a closed six-sided figure
  • Think of where we see shapes: pictures on walls, tables, doors, cabinets, signs, books, etc. Many things have more than one shape (chair with square seat and round wheels)
  • Read: Adler, David A. SHAPE UP!

• Program
  • Hold up a plastic shape and have students practice saying the name of each shape while pointing to it.
  • Have student find shape in a pile of plastic shapes when asked “Would you hand me a square (rectangle, or circle, etc.)?”
  • Have student find something in the room that is given shape. (“Find something in this room that is shaped like a rectangle”) (a door)
  • Scavenger hunt: find five objects containing each shape.
  • Play matching games with the shapes.
  • Creative play - Using the plastic shapes, see how many different shapes you can create. (Ex. two squares make a rectangle, six uniform triangles make a hexagon)
  • Try to make pictures using the tangrams (If the tangrams are popular, there are stories at the library which include illustrations created with tangrams.
