Year 6 Mathematics Lesson Plan: Introduction to Algebra

Duration: 30 Minutes
Subject: Mathematics
Topic: Algebra
Grade Level: Year 6

---

Lesson Objectives

By the end of this lesson, students will be able to:

1. Understand the concept of algebraic expressions.
2. Identify variables, constants, and coefficients in expressions.
3. Simplify basic algebraic expressions.

---

Materials Needed

• Whiteboard and markers
• Algebra tiles (optional)
• Worksheets with practice problems
• Notebook and pencil for each student

---

Introduction (5 Minutes)

Hook

Begin the lesson with a simple question: "What do you think makes up the number of apples in a box if we don't know how many are there?"

Explain briefly that this uncertainty can be represented using letters (variables) and that these are fundamental to algebra.

Explanation

Introduce the concept of algebra as a way to represent numbers using symbols and letters. Outline how it can help in solving problems where the value is unknown.

Direct Instruction (10 Minutes)

Introducing Key Terms

1. Variable: A symbol (often a letter) that represents an unknown value (e.g., x, y).

2. Constant: A fixed value that does not change (e.g., 4, 10).

3. Coefficient: A number used to multiply a variable (e.g., in 3x, 3 is the coefficient).

Example

Write a simple expression on the board, such as:
3x + 5 = 20

• Identify the variable (x), constants (3 and 5), and the coefficient (3).

---

Guided Practice (10 Minutes)

Simplifying Expressions

1. Present students with the following expressions on the whiteboard:

   • 2a + 3a
   • 4y + 6 - 2y

2. Walk through simplifying these expressions step-by-step:

   • Combine like terms.
   • Reiterate that the variables must be the same to combine them.

3. In pairs, have students practice on their own using the following expressions:

   • 5m + 2m
   • 7n - 3n + 4

---

Independent Practice (5 Minutes)

Distribute worksheets with a set of problems for individual practice. The problems should include:

• Identify variables and constants in given expressions.
• Simplifying more complex expressions like:
  • 4x + 2 - x
  • 3a + 5a - 4

---

Closing (5 Minutes)

Recap

Quickly revisit the main points covered in the lesson, asking students to summarise what a variable, constant, and coefficient are.

Questions

Encourage students to ask any questions they may have about today’s lesson.

---

Homework Assignment

Assign students to create three original algebraic expressions and identify the variables, constants, and coefficients in each expression.

---

Assessment

Evaluate student understanding through:

1. Observations during guided and independent practice.
2. Checking the accuracy of answers on the worksheets.
3. Collecting and reviewing homework submissions.

---

Reflection

After the lesson, reflect on what worked well, any challenges students faced, and how future lessons can be improved.
