Please Excuse My Dear Aunt Sally: Order of Operations

Lesson Plan Published 4/27/16 Last updated on 8/14/18

In this lesson, students view a short, fun video to learn about the order of operations using a mnemonic device. Then, they practice applying the order of operations to solve equations of various degrees of difficulty.

Note: This lesson is intended to be used in a flipped classroom setting. It works best when students have access to devices both at home and in class. It can easily be modified to work in other contexts as well. See the differentiation suggestion that follows.

Learning Objectives

Students will be able to:

  • Define the order of operations

  • Apply the order of operations to solve equations of varying difficulty

  • Adobe Spark

    Adobe Spark is an easy-to-use tool that helps you turn your ideas into compelling social graphics, web stories, and animated videos

CCSS.MATH.CONTENT.6.EE.A.2.C - Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). For example, use the formulas V = s3 and A = 6 s2 to find the volume and surface area of a cube with sides of length s = 1/2.

Leaving some of the information or steps out allows student to problem solve together to discover their own steps.​

This lesson didn't allow students be show their creativity, it was shown to them. If the students had had the opportunity to create a​ mnemonic device then creativity assessment would apply. There are no guided questions for creativity.
