Second Graders Welcome A New Math Unit

Our second graders have started a new math unit-basic addition and subtraction facts.  In this unit we are learning and practicing different addition, subtraction, and problem solving strategies.  We are using double facts, making pictures, using number lines, using bar models, and  breaking apart numbers to add and subtract in different ways.  We are even going to learn how to add three numbers together!  Here are some second grade mathematicians hard at work!
