This document is designed to be a 10-day set of warm-ups on fraction-percent conversions. 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 first set is on converting fractions to decimals and percents, and the second set is on converting percents to fractions. These sets could also be used as a practice or test-prep worksheets.
