Permutations and combinations

I like this warm up because Students will take a variety of methods to represent it.  There are only two shapes, and its a quick problem that gets down to the idea of choosing.  

After this I ask them to extend their thinking with this ordered horse race problem:

common student  responses include 3*8, 8^3, 8*7*6

and most student responses are "its the same"
