Record your data on your paper and on the chart on the board. Calculate the average length of the 'inch', 'foot' and 'yard' for the group and for the whole class. Calculate the average length of the three 'units of measure' for all of the classes. Compare the length of your 'inch', 'foot' and 'yard' with the group, class, and total class averages. Use the meter stick to find the number of inches in a meter.
Meter sticks have units called centimeters and millimeters.
State another word using each of these prefixes. Look at the meter stick. On your paper, draw a line which is 10 mm long. Just under that line draw one which is 1 cm long. On your paper, draw a line which is 10 cm long and just under that line draw one which is 1 dm long.
