Lesson Outline

Introduction (5 Minutes)

• Engage the students: Ask the class if they have ever heard the term "multiple" and what they think it means.
• Define multiples: Explain that multiples of a number are obtained by multiplying that number by whole numbers (e.g., multiples of 3: 3, 6, 9, 12...).
• Provide examples: Write a few examples on the board and ask students to contribute examples of their own for other numbers.

Direct Instruction (10 Minutes)

1. Explain the concept of multiples:

   • Define multiples clearly.
   • Write down the first five multiples of the numbers 2, 3, and 5 on the board.
   • Illustrate the multiples using a number line for visual understanding.

2. Introduce common multiples:

   • Define common multiples as those that two or more numbers share.
   • Provide examples using the numbers 4 and 6 (common multiples: 12, 24, etc.).

3. Show how to find common multiples:

   • Use listing and the least common multiple (LCM) approaches.
   • Find the LCM of 4 and 6 together as a class.

Guided Practice (5 Minutes)

• Worksheet activity: Distribute worksheets where students will list the first five multiples of 7 and 8.
• After completion, discuss answers as a class.
• Encourage students to list the common multiples they find.

Independent Practice (5 Minutes)

• Hands-on activity: Give students counters.
• In pairs, have them create their own set of numbers and find their common multiples using the counters (e.g., if the numbers are 3 and 5, have them arrange their counters to show the multiples and identify the common ones).

Conclusion (5 Minutes)

• Review key concepts:

  • Ask students to define multiples and common multiples in their own words.
  • Have a few students share one multiple and common multiple they found during the activities.

• Reinforce learning: Explain that understanding multiples will help them in various mathematical concepts like fractions and ratios.

Homework

• Assign students to find the first ten multiples of a number of their choice and identify any common multiples with another number of their choice. This should be submitted in the following class.

Assessment

• Evaluate students' understanding through their participation in class discussions.
• Review completed worksheets and homework for accuracy in identifying multiples and common multiples.
