This product is perfect for practicing 3-digit subtraction! It is designed for students to work with a partner and take turns solving the different subtraction problems. Each problem includes a chart for students to fill out in order to use place value as a guide. One sheet has some regrouping included, and one does not. You can use these as a worksheet to take up, or laminate them and have students practice using dry erase markers so you can keep them as a math center (this is how I use them)! A preview is available so you can check it out before purchasing!
