Subtraction within 20 Bottle Cap Math Centers where kids fill in the missing differences with bottle caps. Hands on and engaging practice for math centers!
SAVE A TON by grabbing this in the Math Bottle Cap Centers GROWING BUNDLE
to get bottle cap centers for the year and save a ton! The sooner you buy that, the more you save. :)
This pack has 3 different sets and each set has 12 activity cards for 36 cards total for a lot of subtracting within 20 practice.
The recording sheet for students to copy their answers on comes in 2 levels so you can give students all the cards or a smaller set to differentiate for lower learners. You can also mix and match the sets to challenge higher students or create more centers for a lot of review.
An answer key is included so all you have to do is write each answer for the set you're using on a bottle cap with a permanent marker and put those caps in a baggie with the cards to create the center. :)
I also include teacher directions and student friendly directions for you to put in the center if you want it to be an independent center.
Bottle caps are just super fun! I am excited to add a bunch of these to the growing bundle I mentioned above. To see how I use them for phonics, check out:
