This resource contains 24 double digit subtraction with
regrouping strips. On each strip, the students must solve a subtraction fact. There is a recording sheet for the students to place their answer.
There are two versions of this activity. The first version contains just subtraction problems (with regrouping), the second version comes with a QR code. The students can self-check their answer to see if they are correct. If using the QR codes, this makes a great self-checking center station for the students to complete during math groups, rotations, etc.
Can also be used for Math Notebooks
Included is also an answer key, teacher notes for storage (I store mine in a baby wipe container, baggie, or pringles can), and directions for use.
