Students examine four mathematical statements and determine which of the three doesn’t belong.
They are asked to make a claim, provide evidence to support the claim and then explain why the evidence supports their claim.
After they’ve done that, students are asked to provide 4 examples of their own where one doesn’t belong and again provide claim, evidence and reason.
This 2nd stage can be used in multiple ways; students can do the explaining themselves or trade with a partner and have their partner complete the task.
Can be used as station/partner/group work, as a Problem of the Day, enrichment, etc.
