Lesson Plan: Number, Money, and Measure - Order of Operations

Subject: Mathematics Level: Second Level Topic: Number, Money, and Measure

Learning Outcome: Having explored the need for rules for the order of operations in number calculations, I can apply them correctly when solving simple problems.

Curriculum for Excellence Experiences and Outcomes: MNU 2-03a: I can use my understanding of the need for rules in number calculations to solve simple problems.

Resources: - Whiteboard and markers - Number cards - Worksheets with order of operations problems - Money manipulatives (coins and notes) - Measuring tools (ruler, measuring tape)

Introduction (10 minutes): 1. Begin the lesson by reviewing the four operations (addition, subtraction, multiplication, division) with the students. 2. Discuss the importance of following the correct order of operations when solving math problems. 3. Introduce the acronym “BIDMAS” (Brackets, Indices, Division, Multiplication, Addition, Subtraction) as a way to remember the order of operations.

Main Activity (30 minutes): 1. Divide the students into small groups and provide each group with number cards. 2. Ask the groups to create and solve simple math problems using the number cards, following the order of operations. 3. Circulate around the room to observe and assist students as needed. 4. After the activity, come together as a class to discuss the importance of following the order of operations and share some of the problems solved by the groups.

Extension Activity (15 minutes): 1. Distribute worksheets with order of operations problems for students to solve individually. 2. Encourage students to use written and mental strategies to solve the problems. 3. Review the answers as a class and discuss any common mistakes made by students.

Conclusion (5 minutes): 1. Review the key points of the lesson, emphasizing the importance of following the order of operations in math calculations. 2. Ask students to reflect on how they can apply this knowledge in their everyday lives, such as when shopping or measuring ingredients for a recipe.

Assessment: Observe students during the main activity to assess their understanding of the order of operations. Review the completed worksheets to evaluate their ability to apply the rules correctly when solving problems.

Homework: Assign students to create their own order of operations problems for a family member or friend to solve. Encourage them to use different operations and numbers to challenge the solver.
