One more trip up to Boston today for the last Brute Squad practice weekend before nationals. Follow along next weekend and maybe watch some great ultimate frisbee on ESPN:

Before heading out the door we went through a quick Family Math project about mixing. I illustrated the problem using a glass of red liquid and a glass of green liquid. The problem is this:
(1) Take an amount of liquid from the red glass and put it in the green glass.
(2) Now take the same amount of liquid from the green / red mixture and put it back in the red glass.
(3) The question is – does the green glass have more red in it or does the red glass have more green in it?
It is a pretty cool problem for kids to talk through:
After talking about the problem with liquid, we now try a hopefully easier version of the problem using snap cubes. One of the lessons I’m hoping for here is learning to find versions of a complicated problem that are a bit easier:
So, a fun problem for kids that we can do with food coloring and with blocks. Hopefully these two different approaches hope clarify what is a somewhat non-intuitive result.
