Once students worked their way around the room I had them analyse the data from the sample they started with. Here are the results:
Once this was done students filled in a sheet summarizing the reasons that were given. We then went back and looked at the criteria for what makes a good WODB. Here it is:
Students were then instructed to rank the A to O samples individually from strongest 1 to weakest 15 by looking at the samples, the final data of the distribution and comparing this to the criteria.
The back of the room was set up and looked like this for the ranking to occur.
Here are the slips.
And the final averages of the students rankings versus my rankings.

From what I can tell students valued the equal distribution heavily and I valued the distribution and the math equally ( now there is a surprise! ).
Lastly I really liked the structure of this 3 day lesson. I think you could do this in any course  including nonmath courses.
Hope you enjoyed. I did.

Alex  looks like a super fun activity that has a lot of value (especially in the spiralled classroom!)
ReplyDeleteExcited to try something like this. Thanks for sharing!
Thanks Kyle. I think it would be great near the end of the coursemight be more math rich.
DeleteHi Alex, thanks so much for posting the entire process of using WODB in the classroom! Two questions:
ReplyDelete1) How long are your class periods? The day 2 lesson in particular (where the students created their own WODB) seems like it would take a while... (my classes are 42 minutes long.)
2) I struggle with encouraging deeper math thinking too (and I teach ELL's)  any thoughts for next time about extra scaffolding to encourage "better" (i.e. mathematically more rich) WODB's?
Thank you again for these posts!!
Chikae, Classes are 75 minutes. Mathematically more rich WODB's might have happened later in the course. I think I might have modelled making one with them relevant to the curriculum as a model would have helped.
DeleteThank you!
