Week 9 - Measurement
17:22:00How many tools can you think of that help us measure?
Chances are that you immediately thought of a ruler or scale. If you thought of a watch, measuring cup, or a thermometer, give yourself a pat on the back. But don't stop there! Measurement isn't restricted to classifying size, weight, time or temperature. Protractors measure angles, speedometers measure speed, barometers measure air pressure, callipers measure distance, galvanometers measure electric currents, and calendars measure time. There is no end to the amount of measurements we can make in the world around us!

As Drew Brees and Elmo point out in the video above, you can use anything to measure ... even a potato! When young students are first introduced to measurement, this concept of open-ended measurement can be extremely helpful. Students can learn to use everyday objects to estimate the length, width or height of any object, including themselves! Measurement should never be introduced as a restrictive concept with limiting rules. Instead, using open-ended and relative measurement, as well as gamification can help students to view measurement as a site of wonder and inquiry.
