Use the four operations with whole numbers to solve problems. 4.OA.1. Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations. Tasks 4.OA.1 Task 1: Donut Shop 4.OA.1 Task 2: Three Times as Much

4.OA.2. Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.1 Tasks 4.OA.2 Task 1: Selling Candy 4.OA.2 Task 2: Clothing Prices 4.OA.2 Task 3: Fund Raiser 4.OA.2 Task 4: Buying Music
