There are 24 task cards that ask if the commas are being used correctly in either a list, an address, or a date. There are recording sheets if you want to use all 24 at once or 12. There is a second set that is numbered 1-12. They are really numbers 13-24 of the first set. They are numbered 1-12 in case you want to split them up. There are also 2 sets of 3 challenge cards where the students will have to rewrite the list, date, or address with commas in the right spot. There is a colored set and a black and white set of the cards.
