3rd Grade Module 3 Terminology

  • Terminology

    New or Recently Introduced Terms

    §   Even, odd (number)

    §   Multiple (specifically with reference to naming multiples of 9 and 10, e.g., 20, 30, 40, etc.)

    §  Multiplier (the factor representing the number of units)

    §   Product (the quantity resulting from multiplying two or more numbers together)

    Familiar Terms and Symbols

    §   Array (a set of numbers or objects that follow a specific pattern)

    §   Commutative Property (e.g., 2 × 3 = 3 × 2)

    §   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)

    §   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 two expressions are equal, e.g., 3 × 4 = 12)

    §   Factors (numbers that are multiplied to obtain a product)

    §   Multiply, multiplication (an operation showing how many times a number is added to itself, e.g., 5 × 3 = 15)

    §   Number bond (model used to show part–part–whole relationships)

    §   Ones, twos, threes, etc. (units of one, two, or three)

    §   Parentheses (the symbols (  ) used around a fact or numbers within an equation)

    §   Quotient (the answer when one number is divided by another)

    §   Row, column (in reference to rectangular arrays)

    §   Tape diagram (a method for modeling problems)

    §   Unit (one segment of a partitioned tape diagram)

    §   Unknown (the “missing” factor or quantity in multiplication or division)

    §   Value (how much)
