Measure the length of objects aligned to centimeter units. First, use centimeter squares to determine the length. Then, learn how to use a centimeter ruler
A. Count to measure lengths of objects in non-standard units
B. Measure lengths of objects from endpoint to endpoint with no gaps or overlaps
C. Measure lengths of objects by laying non-standard units correctly
D. Compare lengths measured in different non-standard units
E. Count to measure lengths of objects in centimeters
G. Align objects to a centimeter ruler to measure length
H. Draw a line segment of a given length
I. Measure side lengths of 2-D objects using a centimeter ruler
