Three Digit Subtraction Strategy

Teaching math can be hard these days! I have quite a few friends struggling with addition and subtraction with regrouping. I felt like we were getting two-digit and then we had to go to three digit and we got stuck.

Since we do not teach the standard algorithm in second grade, I teach all the strategies and students choose which strategy works for them. One of my go to strategies is the open number line. I love teaching this! I tell students a little story about the three bears, Papa Bear makes big hops, Mama Bear makes medium hops and Baby Bear makes little hops. Kids just love this, and it helps them remember how to count along the number line.

Here's a cute little freebie to help you teach this skill. Click the pic to snap it up!
