Geometry Bulletin Board

no ratings yet

What You Need:

  • Two heavy pieces of corrugated cardboard
  • Pieces of scrap fabric
  • White glue
  • Rubber bands

What You Do:

  1. Have your child glue the two pieces of cardboard together.
  2. Next, he should cover one face of the cardboard with a thin layer of glue. Have him lay the fabric over the cardboard, gently pressing it into place. Fold the fabric over the cardboard as if you were wrapping a gift. Glue the folds into place on the back of the bulletin board. Allow glue to dry.
  3. Ask your son to stretch one rubber band horizontally across the board, dividing it into equal pieces. Can he name the fraction he has created?
  4. Have him add another rubber band horizontally. Shift as needed for even spacing until the bulletin board is divided in thirds. Can he name this new fraction?
  5. Remove the second rubber band and have him add a new one vertically. Again, shift to create even spacing. Can he tell you that he now has four quarters?
  6. Encourage your son to try several more combinations. Can he create fifths? Sixths? Eighths?
  7. When you are done with fraction practice, have him stretch several rubber bands horizontally and several more vertically. Allow your child to stick in photographs, ticket stubs, and more into the rubber band straps.
  8. Display the finished product in his room or let him hang it up in his locker at school!
