Basics:
2 sides to tape (Red and Black)
Red side = cm
Black side = cm with mm markers
Advantages:
Good for measuring curved surfaces
Good for measuring perimeter (Tree example: Measuring Tape or Ruler?)
Tips:
Metal tip can be inaccurate, use 1 cm as starting point
Measure a round object (Ask students if 1 cm is the starting point and the tape reads 36cm, is the perimeter 36cm? or 35cm?
Experiment:
Have students measure the perimeter or circumference of different objects
