here's a ptt. with a worksheet. i pasted the things on the second page on the first page, because I couldn't fit the images on the first word doc.
the last page is just numbers i used in a game. I put the numbers on the bored, then would read a number, and have two students try to smack the number first, whoever got it first won a pt. for their team
i found this useful b/c they weren't too good with thousand and hundred, so this was fun practice.
