Description: This deck includes 15 BOOM Cards, which provide students with practice subtracting 3-digit numbers. ALL questions require regrouping in the tens or hundreds or both. Most questions have a 0 in the tens, but a few are in the ones. The slides are interactive, in that students CAN (are not required to) drag the "slash" to cross off numbers when regrouping.
