Student Outcomes

  • Students use properties of operations to multiply and divide rational numbers without the use of a calculator.  They use the commutative and associative properties of multiplication to generate equivalent expressions. They use the distributive property of multiplication over addition to create equivalent expressions, representing the sum of two quantities with a common factor as a product, and vice-versa.
  • Students recognize that any problem involving multiplication and division can be written as a problem involving only multiplication.
  • Students determine the sign of an expression that contains products and quotients by checking whether the number of negative terms is even or odd.
