A geometry board is a simple peg board that can be used by kids (and adults) to experiment with shapes by simply stretching rubber bands around a grid of nails. My daughter asked me to make one for her and the entire job took about 30 minutes from start to finish.

Step 1: Measuring and Cutting the Board

Here's what you'll need to make a geometry board:

  • a piece of wood (find a piece of scrap in your garage or check the scrap bin at the lumber yard).
  • some kind of saw. I used a table saw and sliding compound saw but a circular saw or hand saw will work fine.
  • carpenter square
  • drill for pre-drilling holes for the nails.
  • sand paper.
  • wax for finishing.

My daughter set the size for this board which is 7" x 7" x 3/4" with 36 nails spaced one inch apart. Start by measuring with a tape measure and making a pencil mark at 7" from the edge. If you have a table saw, rip the board lengthwise.
