This math assessment workbook focuses on proportional relationships and rate problems. Learners set up equivalent ratios to find missing values when the numerator or denominator is unknown. Students engage in exercises involving ratios, fractions, and unit conversions. Sample rate problems include calculating hearts earned per level completed, time required for charging percentages, and determining costs per hour. They translate situations into proportion equations and justify their solutions using cross-multiplication or unit-rate reasoning. Tasks include computing unit rates such as dollars per hour, heartbeats per minute, and percent of battery used per minute. The common core skills identified in this unit are understanding ratios and proportions, performing operations with fractions, and solving real-world mathematical problems involving rates and proportional relationships.
