Logic

I challenged the third graders to coffee bean solitaire! The goal is to get down to just one bean.  I offered prizes for anyone to get down to one, two or three beans.  Lots of fun, lots of groans, and lots of perseverance.  It's a little bit addictive...wish it worked on the iPad, so I could do it while waiting in line at the store.

Three winners so far (each having just three beans left).
