 * Lesson Plan PEMDAS: Math Review Lesson **

**Purpose:** Students will practice the skills of order of operations on the white board while interacting with Dear Aunt Sally for 45 minutes with 90% participation expected. **KUSD Standard:** //I can use parentheses in a number sentence to specify the order of operations. F-8.5// **Context:** Dear Aunt Sally is coming from Florida for a visit. Miss Amy is dressing up as Dear Aunt Sally to help the kids remember the order of operations. This lesson will use white board practice and partner practice in their notebooks. **Planning Ahead:** Materials: **Motivation:** Students will be shocked, intrigued, or terrified by seeing Dear Aunt Sally and this will be the motivation for the lesson. We will begin by introducing Dear Aunt Sally and having the students practice the acronym of Please Excuse My Dear Aunt Sally to remember the order of operations. **Development:** We will begin with a full group review of PEMDAS and introduce or review the acronym “Please Excuse My Dear Aunt Sally”. Then we will work in full group by putting 8-10 problems on the board for the students to help us solve. For the later problems we will try to get the students to come up to the board to do them for their classmates. After those problems, we will partner the students and have them work on two problems from the worksheet. Then we will go over those problems as a class. One thing that we will emphasize during the teaching process is to underline the step you are on. This will cut down on confusion and help with memorizing the order. **Assessment:** We will assess the students on participation. To earn full credit, each student must raise their hand at least 2 times. To earn half credit, students must raise their hand once. No credit will be earned if the students do not participate. **Adaptations:** No adaptations are necessary for these students but if we had students with special needs we could spend more one-on-one time with them. Also, the underlining step is a built in aid for students with special needs.
