Lesson Details:

Introduction (5 minutes)

• Greeting and Objective Setting: Briefly outline the lesson’s objectives.
• Activation of Prior Knowledge: Ask students what they remember about fractions and specifically their denominators and numerators. Use visual aids like fraction strips to illustrate.

Main Activity (12 minutes)

Step 1: Explaining the Concept (4 minutes)

• Explain the concept of a common denominator and demonstrate how to find it for two or more fractions.
• Illustrate with examples: 1/4 + 3/8. Draw visuals on the whiteboard and show how to convert 1/4 to 2/8 to be able to add it to 3/8.

Step 2: Guided Practice (4 minutes)

• Distribute worksheets that contain various fraction addition and subtraction problems.
• Walk through the first few problems as a class, ensuring students understand the process of aligning denominators before performing addition or subtraction.

Step 3: Independent Practice (4 minutes) -Allow students to attempt solving problems on their own or in pairs. Circulate to provide support where necessary.

Conclusion and Assessment (3 minutes)

• Review: Quickly recap the steps for adding and subtracting fractions.
• Formative Assessment: Ask students volunteer answers for one of the problems and explain their thought process. Provide immediate feedback.

Extension Activities (Optional, post-lesson)

• Suggest students to visit NZ Maths for interactive activities and additional practice problems specifically tailored for Year 8 students.

Homework:

• Assign additional problems from the worksheet for extra practice.

Reflection and Notes:

Post-lesson, reflect on student engagement and understanding:

• Which concepts did students grasp quickly, and where did they struggle?
• Adjust future lessons based on these observations to cater to identified learning gaps or misconceptions.
