 Computation and Estimation Focus: Integer Operations and Proportional Reasoning The student will solve single-step and multistep practical problems, using proportional reasoning. HCPS Course 2 Curriculum Guide
 Essential Knowledge and Skills Write proportions that represent equivalent relationships between two sets. Solve a proportion to find a missing term. Apply proportions to convert units of measurement between the U.S. Customary System and the metric system. Calculators may be used. Apply proportions to solve practical problems, including scale drawings. Scale factors shall have denominators no greater than 12 and decimals no less than tenths.  Calculators may be used. Using 10% as a benchmark, mentally compute 5%, 10%, 15%, or 20% in a practical situation such as tips, tax and discounts. Solve problems involving tips, tax, and discounts. Limit problems to only one percent computation per problem. Essential Understandings What makes two quantities proportional? Two quantities are proportional when one quantity is a constant multiple of the other.
