  • Repeated multiplication of a number times itself; 33 = 3X3X3
  • Exponents in Expression, where students get to work within parentheses; 2+53 = 2 + (5X5X5).
  • Slowly, students get introduced to order of operation by solving exponents in expressions.

  • Third-grade get to do basic order of operation with additions, subtractions, and multiplications.
  • In Six-grade, exponents are added to additions and subtractions, where students have to follow steps to order of operations.
  • One strategy for order of operation is the order of pyramid. There are three levels to order of pyramid; 1. Exponents, 2. Multiplication and Division (from left to right), 3. Addition and Subtraction(from left to right).
