This review focused on understanding decimals and converting between fractions and decimals. Students learned to write decimals from fractions with denominators like 10, 100, or 1000 by placing the decimal point accordingly. They also practiced changing decimals into fractions by removing the decimal and adjusting the denominator. The unit included adding and subtracting decimals through real-life problems, such as finding totals and differences in money, mass, temperature, and distance. Exercises reinforced these concepts with fill-in-the-blanks, conversions, matching, and word problems for better application and practice.
