Formative Assessment -- Laundry Day

I found this interesting idea for formative assessment that I would love to collaborate on. 

I am looking for Math 30-2 and Math 20-2 teachers willing to work on one unit for Laundry Day. Please email me if you are interested and let me know what unit you want to work on so we don't duplicate.  Hopefully we can get all the units done this year.

Here is the idea from Senora Munoz (http://fai.tie.wikispaces.net/file/view/1a_WY+State+Conf+HOs.pdf)
