Background Knowledge
In this lesson plan on algebraic expressions for class 7, students should have a basic understanding of mathematical operations (addition, subtraction, multiplication, and division) and the order of operations (PEMDAS) to simplify expressions correctly. They should also be familiar with the concept of variables as symbols representing unknown values in simple equations. Prior exposure to applying math in real-world contexts, such as budgeting or measurements, will help them relate to the lesson's practical applications. Additionally, students should possess foundational group collaboration skills to engage effectively in team-based problem-solving activities during the lesson.
Skills
Critical thinking , Problem solving
Objectives
Students will be able to identify and define terms, coefficients, and variables in algebraic expressions.

Lesson Activities
Introduction (5 minutes) 🎬
Begin with the provocative question: "How can algebra help you plan a party?" Show a short video clip of a real-world scenario involving budgeting for a party, which introduces the concept of using algebraic expressions to manage costs.
Teacher Note
Ensure the video is engaging and relatable to the students' interests.
Present New Material (10 minutes) 📊
Use the interactive whiteboard to introduce algebraic expressions, breaking down terms, coefficients, and variables. Demonstrate with visual aids and storytelling, explaining how each part of an expression represents a real-world quantity. Use algebra tiles to show how expressions can be simplified.
Core Questions
"What is a variable?" "How does a coefficient affect a term?" "Can you identify the terms in this expression?"
Teacher Note
Use relatable examples, such as "3x" representing the cost of 3 pizzas.
Guided Practice (10 minutes) 👫
Divide students into small groups and give each group a set of real-world problem cards. Each group uses algebra tiles to model and simplify the expressions on their cards. Circulate the room to provide immediate feedback and support.
Teacher Note
Encourage collaboration and ensure each student participates in the activity.
Individual Practice (10 minutes) ✍️
Distribute printed worksheets with a variety of structured problems. Students work independently to simplify expressions and solve problems, using mini whiteboards to show their work. Provide immediate feedback as they work.
Core Questions
"How did you simplify this expression?" "What steps did you take to solve this problem?"
Teacher Note
Monitor students' progress and offer guidance to those who are struggling.
Assessment and Reflection (10 minutes) 📱
Use an online quiz tool to conduct a quick formative assessment, ensuring students understand the key concepts. Follow this with a reflective journal entry where students write about how algebraic expressions can be used in their daily lives.
Teacher Note
Look for understanding of terms, coefficients, and variables in the quiz results. Encourage honest reflections in journals.
Review and Closure (10 minutes) 🗣️
Conduct a class discussion to review key concepts, encouraging students to share their reflections and problem-solving strategies. Emphasize the real-world applications of algebra. Conclude with a collaborative activity where students create and solve their own algebraic expressions based on a given real-world scenario.
Core Questions
"Can you think of another real-world problem that can be solved using algebra?" "How did you create your expression?"
Teacher Note
Celebrate students' creativity and problem-solving skills. Ensure every student feels valued and heard.
