This Instructional Activity is a part of the Lesson 3, Unit 5, Grade 6. In this activity, students encounter two variations of decimal subtraction in which regrouping is involved. They subtract a number with more decimal places from one with fewer decimal places (e.g., 0.1 - 0.035), and subtract two digits that represent the same place value but where the value in the second number is greater than that in the starting number (e.g., in 1.12 - 0.47, both the tenth and hundredth values in the second number is larger than those in the first).
