This six-page document is designed to be a 10-day set of warm-ups on multiplying decimal numbers. There are two sets of five-day warm-ups. For each set the first three sections/days are computational practice. The fourth section/day is a constructed response type question where students are asked to show work and explain how a solution is determined, and the fifth section/day is a set of five multiple-choice questions. The set is multiplying decimal numbers by whole numbers, and the second set is multiplying decimal numbers by decimal numbers. These sets could also be used as a practice or test-prep worksheets.
