I use math card games for my math homework. I have tried EVERYTHING in the past for math homework and nothing, NOTHING, my friends, has been more successful than math card games. I have parents tell me all the time how much fun they have as a family when playing these games. I've even had older and younger siblings tell me they have fun playing math card games. All I do is copy on fun colored paper, cut and send home each Monday. I also throw these in my math rotations at times.
The only problem is (please don't tell) that I've been using 3rd grade aligned card games for my 4th graders! Gasp! I know! So, I am going to make a whole set of 4th grade aligned card games. So far I have four games for you. They are all yours. Just click the pic and enjoy! All the games are free in my TpT store.
*Update - because of the awesome response (emails just keep coming) I've created a set of NBT card games and will be making the other standards soon. Click here to visit my TpT store if you would like.
