#### Introduction (10 minutes):
1. **Greeting and Roll Call**
- Welcome the students and take attendance.
2. **Warm-up Activity**
- Begin with a short discussion about patterns and sequences. Ask students to observe patterns around them (e.g., the number of days in a week, number of fingers on a hand).
3. **Objective Overview**
- Briefly explain what they will learn in this lesson: "Today, we'll explore algebraic processes. We'll learn what variables and constants are, and how to perform some basic operations with them."

#### Direct Instruction (15 minutes):
1. **Introduction to Algebra**
- Explain the basic concepts of algebra, using simple language and examples:
- **Variable**: A symbol (usually a letter) that represents an unknown value (e.g., x, y).
- **Constant**: A fixed value that does not change (e.g., 3, -5).
- **Coefficient**: A number multiplying a variable (e.g., in 3x, 3 is the coefficient).
2. **Writing Algebraic Expressions**
- Provide examples of simple algebraic expressions (e.g., 2x + 5, 3y - 7).
- Show how to identify the components of the expression (variables, constants, coefficients).
3. **Addition and Subtraction of Algebraic Expressions**
- Demonstrate how to add and subtract terms:
- Like terms (terms with the same variable) can be combined.
- Example: 2x + 3x = 5x; 4y - 2y = 2y.
---
#### Guided Practice (15 minutes):
1. **Teacher-Led Examples**
- Work through a few examples on the board, highlighting the steps:
- Example 1: 5x + 3 + 2x - 1
- Combine like terms: 5x + 2x = 7x; 3 - 1 = 2
- Final expression: 7x + 2
- Example 2: 4y - 2y + 6 - 3
- Combine like terms: 4y - 2y = 2y; 6 - 3 = 3
- Final expression: 2y + 3
2. **Student Practice**
- Provide students with similar problems to solve in pairs or small groups. Walk around the classroom, offering individual assistance as needed.
---
#### Independent Practice (10 minutes):
1. **Worksheet Activity**
- Distribute worksheets with a mix of algebraic expressions for students to simplify.
- Encourage students to work independently to consolidate their learning.
---
#### Closure (5 minutes):
1. **Review and Recap**
- Summarize the key points: identifying variables and constants, combining like terms, and simplifying expressions.
- Allow students to ask any final questions.
2. **Homework Assignment**
- Assign a few practice problems for homework to reinforce the day's lesson.
---
#### Assessment:
- **Formative Assessment**: Monitor student participation during guided and independent practice. Provide immediate feedback and assistance.
- **Summative Assessment**: Evaluate the completed worksheets and homework to gauge student understanding of algebraic processes.
---
#### Reflection:
After the lesson, reflect on the successes and areas for improvement. Note any students who struggled and might need additional support in future lessons.
