This is a set of 32 task cards, each with an elapsed time word problem. The problems ask students to go both backwards and forwards in time or to calculate how much time has elapsed. There is a wide range of difficulty levels included so even your high-level students will be challenged. Also included is a student answer sheet where students record their answer then indicate whether they got the answer right or wrong. Students can self-check by using the answer key included. This is also available in a QR format.
