Massachusetts Curriculum Frameworks
MA.6.RP. Ratios and Proportional Relationships
6.RP.A. Understand ratio and rate concepts and use ratio and rate reasoning to solve problems.
6.RP.A.3. Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
6.RP.A.3.d. Use ratio reasoning to convert measurement units within and between measurement systems; manipulate and transform units appropriately when multiplying or dividing quantities. For example, Malik is making a recipe, but he cannot find his measuring cups! He has, however, found a tablespoon. His cookbook says that 1 cup = 16 tablespoons. Explain how he could use the tablespoon to measure out the following ingredients: two cups of flour, 1/2 cup sunflower seed, and 1 1/4 cup of oatmeal.
