This package offers two sets of task cards with 24 cards in each set. This is great practice for addition and subtraction with regrouping. Each set is a combination of both operations.
There is a student answer sheet for each set and an answer key for each.
This is great practice for students who might need extra drill or for those early finishers that you want to provide with a meaningful review. Extra packs of cards could be given to students for individualized homework assignments.
