Description: Practice subtracting two digit numbers with borrowing or regrouping. Each card has a "borrow" for students to practice on. Cards are drag and drop for each digit of the answer. There are a total of 40 cards. Students are given a random 12 cards out of those 40, so each time they play it gives them a unique practice time. All cards give immediate feedback and allow the students to change their answer when incorrect.
