Math Bingo Blues

Alex pulled out some subtraction skills he's been hiding from me in a rousing game of Math Bingo today.  Although I'm posting pictures of his frustration, it's only because these were (in my opinion) the cutest, and also the only ones I was able to shoot from my lap as I was jumping up with excitement on all the ones he got right.  Always been strong with his reading and vocabulary, it's fun to watch him start to excel at something that started off so challenging for him.  This is what I want to remember.
