Math Replacement Update March 4, 2016 Topics Covered Topics Covered Students review the relationships among metric units and practice converting measurements. Students examine the millimeter marks on their centimeter rulers. They measure line segments in millimeters and centimeters. Then they measure illustrations of various invertebrates in millimeters and convert their measurements to centimeters. Students review adding and subtracting decimals. Students review magnitude estimates for whole number division. They make models for division number stories, and they use a division algorithm to solve number stories and interpret the remainders. Students develop and apply rules and strategies for converting between decimals and percents. Students review finding a percent of a number and then solve number stories that involve finding percents of numbers. Students review addition, subtraction, multiplication, and division of proper, improper, and mixed fractions. Students learn traditional algorithm for division with whole numbers and decimals.
