We have begun our math unit on 2-digit subtraction. Starting tomorrow, we will look at two different methods for solving subtraction problems.

We will continue to explore the relationship between ones, tens, and hundreds. Below are the steps for each method. Look for parent letters with examples.

Ms. BedfordI have been teaching for 22 years. When not at school, I enjoy traveling, knitting, and getting together with family and friends. My cat Gilmore brings me laughter with her silly antics. It is a joy to watch children learn and grow during the school year! Archives
