Order of Operations Lesson Plan

Introduction to Order of Operations

10 Min

Begin the lesson with an engaging hook to capture students' interest. Ask the class a provocative question: 'What would happen if we all had different rules for solving math problems?' Follow this with a brief real-world problem: 'Imagine you are a detective trying to crack a secret code. To find the correct sequence, you need to follow specific steps. If you don't, the code won't work!' Introduce the concept of the order of operations and explain that mathematicians use the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to remember the sequence. Provide a simple example on the board, such as 3 + 2 × 5, and solve it incorrectly by not following the order of operations. Then, solve it correctly using PEMDAS.

Direct Instruction and Examples

20 Min

Present the new material in structured, manageable chunks. Explain each component of PEMDAS with examples: - Parentheses: (2 + 3) × 4 - Exponents: 2^3 + 1 - Multiplication and Division (from left to right): 6 ÷ 3 × 2 - Addition and Subtraction (from left to right): 5 - 2 + 3 Use a video to visually demonstrate the steps of solving an expression using PEMDAS. Distribute a worksheet with a variety of expressions for students to solve in pairs using the Think-Pair-Share method. After pairs have discussed their solutions, go over a few examples as a class, ensuring to address common mistakes and misconceptions.

Guided Practice

15 Min

Distribute task cards with different expressions to each group. Use the Jigsaw Method where each group solves their assigned expression and then teaches their solution process to the class. Provide immediate feedback and address any errors or misunderstandings. Use a Rule Table to summarize the steps of PEMDAS and display it prominently in the classroom. This will serve as a reference for students during the lesson.

Independent Practice

10 Min

Assign a set of problems on a worksheet for individual practice. Ensure the problems vary in complexity to cater to different skill levels. Encourage students to refer to the Rule Table and their notes. Walk around the classroom to provide assistance and monitor progress. Use a quick formative assessment by asking students to write a One-Minute Paper on what they found most challenging about using PEMDAS and how they overcame it.

Assessment and Reflection

10 Min

Conclude the lesson with a brief review of the key points. Use a Jeopardy game to assess students' understanding in an engaging way. Include questions that require students to solve expressions using PEMDAS and explain their reasoning. Finish with a reflection activity where students share one thing they learned and one question they still have. Use a Summary Excerpt to provide a concise overview of the lesson's key points and distribute it as a handout for students to review at home.
