Last day for measuring with rulers.

Talk about a few things to begin with: students have been measuring by overlapping their rulers so the ruler ends exactly at the end of the object they are measuring. Can you put the rulers end-to-end and measure that way? How would you know when to stop?

Students have a last chance to make estimates and measure classroom objects that are larger than their ruler. At the end, share some observations, discoveries, etc.
