A1-43: CROSSING RODS

A1 43 3

Additional Info

  • ID Code: A1-43
  • Purpose: Visualize three-dimensional figures
  • Description:

    Plastic frame with two colored rods. The trick here is to determine, solely by looking at the frame from two sides set 90o apart (as seen above) whether the sticks are touching or not.

    This can be useful when discussion ideas of perspective and imaging. Try showing the model from a single angle, perhaps with a video camera, and invite students to draw it; then rotate it and have them compare their results.
