Today I wanted to do some math work sheets (I had addition in mind) with Coryn. It was easy enough to find some (just google "addition work sheets" or something like that. There are a ton of free resources out there), but apparently being out of gray ink means I can't print black and white worksheets (what sort of printer has a cartridge specifically for gray ink? Mine, apparently.). So I had to improvise.
A couple years ago I bought two separate sets of dominoes on clearance: one with numerals, the other with the more traditional dots. From there it was pretty easy to form a plan. I opened them up and started matching the dot dominoes to the identical numeral dominoes as seen below.
I put the first set in front of Coryn, asked her to name the numbers then count the dots. Then said, "So six and six is. . ." and let her fill in the blanks.
We went through the entire sets (except for any with blanks. Since the blanks aren't a zero I didn't feel the conveyed the equation as well as I'd like.) and then played a quick game of dominoes just for the heck of it.
