I think the dot game is yet another brilliant method of teaching high level math to kids. Maria Montessori seemed to have a special kind of brilliance for taking difficult concepts and making them concrete. The trouble is that it seems they're expected to use their dot game paper for one single math problem... and then what? Recycle it? This gets expensive (AND WASTEFUL!) very, very fast. Especially when your daughter thinks the dot game is about the coolest thing ever and wants to do it all.the.time. That's what you want, but not when it drains your pocket book! I had been just printing it off and letting her use it that way, but then we went through a phase where she was sort of uninterested in doing any school at all and since it's summer I just let it be for a while.
Starting up again, I wanted something fun and exciting and nice to look at. So I broke out my old scrapbooking stuff and found a pretty "dot" paper. I printed off a copy of the dot game paper from this site and cut it out. I stuck it on with tape because I didn't want to take the time, but if I had it to do again I'd use a glue stick or something to stick it on since it does seem to pop up a little funny in the middle of the paper. Then I stuck on the letter stickers to say "The Dot Game". Finally I used self adhesive laminating sheets to laminate it and then cut off the excess.
She's using embarrassingly large dry erase markers in the appropriate colors, but I'd like to get some that are a better thickness for the size of the dot game. These are just what I happened to have on hand.
I love that I don't have to print off a thousand copies of the dot game paper and my daughter can math to her little heart's delight!
