[Lesson Plan] Order of Operations
"Class, what is the Order of Operations?" My energetic class of fifth graders shouted out loud, "Please Excuse My Dear Aunt Sally!" What? Who is Aunt Sally? When students initially learn how to add, subtract, multiply, and divide, they are taught to perform those skills using two numbers and one operation. As they progress to the next levels, they begin to see numerical expressions with more than one operation and word problems that involve multiple steps. Introduce your students to the Order of Operations - and help them memorize the "PEMDAS" or "Please Excuse My Dear Aunt Sally" acronym as early as third grade. Putting this memory into practice can be more of a challenge - so we've come up with some tips and a fun lesson plan activity for your students to drive the concept home!
