What are two things we can measure about the object on the teacher’s desk?
What are three tools that we use to measure things?

4. Activity #1: Measuring Tools

(What would you need to tell them?)
How many paperclips long was your desk?
Why do we all have different answers?
What did you do when the measurement did not come out to be a whole number?
What steps could we take in order to ensure we all got the same measurement?
Do all countries use the same measurements?

6. Standard Measurement
When measuring anything you must have a universal standard to compare to…
The Foot: originally based on the body part
The Meter: there used to be a metal bar that had two lines scratched in it. That used to be “One Meter”
The Kilogram: there is a piece of metal in a building in Paris that is “One Kilogram”
