Your students will really enjoy measuring things with their mustache ruler. There are 10 different measurement activities included.

Make sure you print the mustache ruler so it is to scale.  When I made my template I measured it with a ruler to come out exactly at 10 inches, however some printers print this off at a tiny bit smaller scale. Simply measure your template to make sure it is correct.  If not, click enlarge when you make your hard copy and then measure again.
