Weight, Area, and Rate Problems

Mr. Richards reviews practice problems for Grade 6, Unit 3, Lesson 9. The video covers solving a cheese cost problem using unit rates, calculating copy machine output with tables, converting weights to order objects by weight, comparing earnings from lawn mowing jobs, and performing decimal calculations. The lesson concludes with finding the area of a polygon by decomposing it into simpler shapes.
