Comparing Ratios and Rates

Mrs. Hazmer's lesson focuses on comparing ratios using ratio tables. The classwork involves creating equivalent ratios by scaling up and down. Students learn to describe ratio relationships in tables and compare rates, such as texting speeds and juice concentrate ratios. Exercises include comparing water to juice ratios and determining the strongest apple juice taste. The lesson concludes with comparing orange juice and smoothie recipes.
