This is a set of 32 task cards, each with a multi-step word problem to fit the 4th grade common core math curriculum. These cards are great for math centers, to use as game cards with a generic game board, or for a scoot activity. There are more than enough cards for the whole class to participate at once. Students can self-check by scanning the QR code on each card or by using the answer key included. This is also available in a non-QR format.
