This Problem Set is a part of the Lesson 24, Unit 4, Grade 2. In this lesson, students continue to use decomposition of the minuend to subtract a two-digit number from a three-digit number. They use place-value disks to represent breaking apart three-digit minuends and subtract from the hundred. For example, students restate 143 - 90 as 100 - 90 + 43.
