Here is a set of superhero addition math facts within 20, which is aligned to the Common Core. Great fluency practice for students of any age. Print in color on cardstock for extended use.
Engage all students by first having everyone stand up. Then, go around the classroom showing each student a card. If students get the math fact correct, they sit down. If they are incorrect, then students stay standing. Keep returning to students until they get one fact correct. The goal is for all students to be seated as quickly as possible. Have class help decide on a reward to work towards to increase motivation. Overall, this activity is a great way to hold all students accountable for their own learning.. AND for each others! (May need to teach students how to positively encourage other students before doing this type of activity). Also, I keep this set of flash cards in our math area so students can practice these during Math Daily 3 centers, or for early finishers.
