Which One Doesn’t Belong (WODB)

WODB

Similar to compare and contrast.

Helps students identify properties and characteristics.  

Teacher starts by asking students to find a reason why one of the quadrants doesn’t belong.  After a short time, ask students to find as many reasons as they can, why each of the options doesn’t belong.

How might we process this activity?

Whole class discussion:  

  • Poll for answers, then discuss, highlight concepts you have been looking at.  Are there any new ideas?
  • Ask groups to explain how they can arrive at a particular list item (so everyone understands concepts you want to highlight.)  E.g. Define what an intercept is. How can you find them in a graph? In an equation?
  • Can you find any errors or inconsistencies in the list?

Or, could do poster or swap meet…

In a gallery walk: What was the same as yours?  What was different? Do you agree or disagree and why. Questions/Concerns?

Debrief

  • How might this be useful?
  • Can everyone participate?
  • When would it be helpful?
