4.16

The student will

a)   recognize and demonstrate the meaning of equality in an equation; and

b)   investigate and describe the associative property for addition and multiplication.

Essential Knowledge and Skills  (Full Curriculum Framework for this SOL)

  • Recognize and demonstrate that the equals sign (=) relates equivalent quantities in an equation.
  • Write an equation to represent equivalent mathematical relationships (e.g., 4 X 3 = 2 X 6).
  • Recognize and demonstrate appropriate use of the equals sign in an equation.
  • Investigate and describe the associative property for addition as (6 + 2) + 3= 6 + (2 + 3).
  • Investigate and describe the associative property for multiplication as (3 x 2) x 4 = 3 x (2 x 4).

Instructional Note:

The associative property for addition states that the sum stays the same when the grouping of addends is changed [e.g., 15 + (35 + 16) = (15 + 35) + 16]. The associative property for multiplication states that the product stays the same when the grouping of factors is changed [e.g., 6 × (3 × 5) = (6 × 3) × 5]. Note that the order of the addends/factors does not change.
