Reflection: Adjustments to Practice Subtracting Doubles - Section 3: Practice the Concept


During this lesson the students really understood how many different strategies they could use to solve the subtraction problem.  Many students are comfortable using a number line or hundred chart as their go-to resource to help them solve the addition and subtraction problems.  It is my goal to get them to use those as mental models. But it is important for them to understand that they can use other strategies, such as thinking about the related addition problem, to help them solve subtraction facts
