This activity includes a total of 32 task cards with QR codes for students to check their answers. The first 16 task cards contain 3-digit addition and subtraction computation problems, with and without regrouping. The last 16 task cards are one step 3-digit addition and subtraction word problems that contain QR codes for students to check their answers. These problems also include addition and subtraction with and without regrouping. Each of the 16 task cards contain a recording sheet and answer document in case your students do not have access to an electronic device with a QR code reader.
I laminate these task cards, so that I can use them year after year. Students are also able to write on the cards with dry-erase markers.
Great for math centers, independent practice, or a scoot activity.
