In this Illustration students are investigating what samples of 5 rectangles will give them the best estimate of the average area of a set of 100 rectangles. They generate and test two ideas for how to take samples—having their peers choose 5 random numbers and using those numbers to select samples and having their peers choose 5 rectangles by looking at the rectangles—and then they begin to discuss the difference in the two estimates their two methods generate.

Summer 2015 Facilitator Institute
We are offering a Facilitator Institute for those interested in learning how to lead the 20-hour PD course we have developed which uses the Illustrations, along with other student work and planning activities, to support teacher learning about the Standards for Mathematical Practice. The institute will be running from August 3 - August 6, 2015 and is free of charge. For more information contact us at firstname.lastname@example.org.
