16mm MEASURING AREAS: SQUARES, RECTANGLES (1960)!  Just a couple of kids trying to make a gameboard for checkers.  Discussion of how to calculate areas & its use from day to day.  The past!  Fun fun fun.  Good times!  

On one 400' reel.  Some general wear througout  (see screen shots for details).  No vinegar! 

Please don't hesitate to ask questions.

Thank you for looking!!
