This Problem Set is a part of the Lesson 6, Unit 5, Grade 2. In this lesson, students use the compensation strategy--an application of the associative property--to subtract from three-digit numbers. They learn to add or subtract the same number from both terms in a subtraction expression in order to make an equivalent problem that involves no renaming. For example, when subtracting 610 - 290, they might add 10 to both numbers in order to create the equivalent problem 620 - 300.
