This file contains 24 task cards with 3 digit subtraction with regrouping. There is one set of task cards with QR codes for students to check answers, and there is an identical set without the QR codes. The recording sheet and answer key are included.
***Regrouping is only done in either the ones or tens place, not both.
Task cards are a great tool to use in your classroom. You can use them in small groups, in math centers, or as independent work. Just print the cards, cut them out, and laminate them.
QR codes are a fun way for students to check their work with an answer key. The students can scan the QR codes on the card to check their answer on their recording sheet. You will need an electronic device with a QR code reader to scan the QR codes. This would make a great math center or small group activity.
