OK. So maybe this will work. I think I have uploaded my flipchart to googledocs. Still not sure how to upload a cute picture for the preview on googledoc, but it's a start. I created this flipchart to help the students write number sentences and to also see that it doesn't matter which number I add first. The kids can see that 5+2=7 and 2+5=7. Let me know if you download it :) I hope it works!!

Click here for the flipchart. Can't seem to get my picture to link to googledoc.
