Ch. 6 Solve two-step word problems involving all four operations and assess the 3.OA.8 reasonableness of answers Ch. 7 4 3.OA.1 Ch. 8 3.OA.2 Ch. 9 3.OA.4 Ch. 12 3.OA.6 End of Unit Assessment administered: Approximately October 24 Essential Question: How are multiplication and division related? How do we use multiplication and division to solve problems? What are the properties of multiplication? What strategies can we use to memorize facts? Key Vocabulary: Array (a set of numbers or objects that follow a specific pattern, a matrix) Column (e.g., in an array) Commutative Property/Commutative (e.g., rotate a rectangular array 90 degrees to demonstrate that factors in a multiplication sentence can switch places) Equal groups (with reference to multiplication and division; one factor is the number of objects in a group and the other is a multiplier that indicates the number of groups) Equation (a statement that 2 expressions are equal. E.g., 3 × 4 = 12) Distribute (with reference to the Distributive Property; e.g. In 12 × 3 = (10 × 3) + (2 × 3) the 3 is multiplier for each part of the decomposition) Divide/division (partitioning a total into equal groups to show how many equal groups add up to a specific number. E.g., 15 ÷ 5 = 3) Fact (used to refer to multiplication facts, e.g., 3 2) × Factors (i.e., numbers that are multiplied to obtain a product) Multiplication/multiply (an operation showing how many times a number is added to itself e.g., 5 3 =15) ×
