These problem solving task cards are for 2 digit addition and subtraction with and without regrouping. Some of the word problems contain missing numbers to fit the common core standard 2.OA.1
Put these on a ring for early finishers or a work station, center, or rotation or play the game Scoot, Numbered Heads Together or other cooperative group activity! It also works well for small groups or a problem of the day. Answer key and a recording sheet are included. There are 30 cards.
