Which One Doesn't Belong

Find more like this at wodb.ca


Let's begin with some Mental Math...

  1. Silently, think about “which one doesn’t belong” & why
  2. Turn and talk with a partner, which one did you pick? Why?

Talk to your partner about which one you think your students would pick? Why?

What is your proof?

How are you reasoning and applying your mathematical understanding?

Convince others!

What does this sharing sound like?

An Effective Communicator

Find a reason why each one does not belong.

NUMBER 15 from Joe Schwartz wodb.ca/numbers.html

The "Which One Doesn't Belong" website has several examples of open ended thinking tasks. It is an open source site, so you will want to work through the problems yourself prior to using them with your students in order to allow you to determine a reason why each square does not belong- it also is a good way to anticipate your students' answers.
