Counting Back and Counting Up Subtraction Strategy - Mental Math Strategies
This subtraction strategy unit provides practice with two different, but related, beginning subtraction strategies – counting back and counting up. Counting back involves beginning with the bigger number (minuend) and counting back. For example, to solve 8-3, begin with 8 and count back, “7, 6, 5.” This strategy should not be used when the subtrahend is higher than 4. For example, using counting back to solve 16-11 would not be effective, because it would be easy to make mistakes and get mixed u

Compensation Subtraction Strategy - Mental Math Strategies
This unit is part of the subtraction portion of the Mental Math Strategy Collection.This subtraction strategy unit provides practice with the compensation strategy.When we use compensation, we adjust one of the parts in the problem, then make up for that adjustment later. For example, suppose we are solving 36-9. Since 9 is close to 10, we could begin by subtracting 10 to make 26. But now we must make up for that adjustment. We subtracted one too many, so now we add that one back to make 27. So

Break Apart Subtraction Strategy - Mental Math Strategies
Breaking apart numbers by place value is a powerful mental math strategy for addition or subtraction. When we decompose a subtrahend (the number being subtracted), it can make an equation easier to solve. Let’s try this for 45-24. We can begin by breaking apart the 24 into a 20 and a 4. First, we will subtract 45-20 to equal 25, and then we’ll subtract the remaining 4 to equal 21.It’s important for students to understand that there is no one right way to break apart a problem.
