PRODUCT DESCRIPTION

This is a interactive activity designed to be projected for students to work on. Students look at a 3 digit subtraction problem and determine whether or not they need to regroup. They tell their choice using the American Sign Language symbols for R (regroup) and N. (no regroup). Once they make that decision, students practice using open number lines, counting up, counting back and place value to solve the problems. On the final page of this activity, students look at a subtraction problem and tell whether it was solved correctly or not.

This file is zipped. I built this product in ActiveInspire. however I have also included a pdf. I think the pdf might be useful for small group instruction.
