Description: This deck of Boom Cards uses decomposing to model regrouping for subtraction of three digit numbers. Each problem will take 4 slides to complete as it walks them through each of the following steps: 1. The first slide will have students decompose the numbers. 2. The second slide will have them regroup to subtract the ones. 3. The third slide will have them regroup to subtract the tens. 4. The final slide will have them subtract the hundreds and type their final answer in the box. There are diagonal slash marks for students to drag and drop to show their work as they regroup. There are 40 cards in this set for a total of 10 problems.
