5th Grade Topic 2 Assessment Review

The video tutorial covers decimals, including rounding, comparing, adding, and subtracting. It provides examples of rounding decimals to the nearest tenth and estimating sums. The tutorial also explains solving equations with decimals using inverse operations and using models for money calculations. It includes exercises on matching expressions with decimals, calculating distances, and determining perimeters with both rounded and exact values.
