Description: These Valentine's Day decks help students practice double digit addition and subtraction with and without regrouping. Without Regrouping: The slides direct students to add or subtract the ones first and then the tens. Each slide gives a multiple-choice option for every problem. If students do not see their answer have them redo the problem prior to pressing submit. With Regrouping: Every other slide asks students if they need to regroup. Students will answer yes or no to get to the next slide. If the problem requires them to regroup, the next slide will give the students boxes to regroup and boxes for the answer. If the answer is no to regrouping, the next slide will only give them boxes for the answer.
