このクラスで学べること
This class will be a mix of addition and subtraction word problems that involved 2 or 3 steps to get the final answer. We will review part and whole and on each problem discuss how we decide if we will add or subtract. We will solve a few problems together and then the students will work on a problem on their own. Students will be able to ask for help whenever needed. The biggest part of common core math is that it wants the students to be able to explain what they did and why they did it. In this class students will practice talking about the steps they took and why they chose to solve the problem a certain way.
