This lesson builds on students' understanding of ratios by using a recipe to calculate unit ratios from fractional amounts. Students use ratios and proportional reasoning to correct a cooking error which relates to unit ratios. Students use strategies such as making a table or using multiplicative reasoning. This builds toward finding unit rates and ratios using fractional amounts as well as applying understanding of fraction multiplication and division. Big Ideas: Understand that the relationship between the quantities in a ratio is proportional and can be computed using a ratio table or multiplicative reasoning. Understand how to compute a unit ratio using fractional amounts. Vocabulary: ratio table, multiplicative reasoning, multiplicative inverse, reciprocal Special Materials: Measuring cups and spoons (optional)
