Lesson Plan: Factors and Multiples

Subject: Mathematics

Grade: 4

Duration: 30 Minutes

Topic: KY.4.OA.4 - Find Factors and Multiples of Numbers in the Range 1-100

---

Objectives

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

1. Define and identify factors of whole numbers from 1 to 100.
2. Find all factor pairs for a given whole number in that range.
3. Understand the difference between factors and multiples.

---

Materials Needed

• Whiteboard and markers
• Chart paper and markers
• Worksheets with practice problems
• Pair of dice (optional for games)
• Interactive math game (online or offline) for factors and multiples (optional)

---

Introduction (5 Minutes)

1. Hook: Begin with a simple question: “What do you think makes a number special?” Listen to a few responses related to factors and multiples.
2. Define Factors: Write the definition on the board - “Factors are numbers we can multiply together to get another number.”
3. Define Multiples: Write the definition for multiples - “Multiples are what you get when you multiply a number by an integer.”

Direct Instruction (10 Minutes)

1. Identifying Factors:

   • Use an example, such as the number 12.
   • Write the factors of 12 on the board: 1, 2, 3, 4, 6, and 12.
   • Show how to find factor pairs: (1, 12), (2, 6), (3, 4).
   • Explain that there are no other combinations of whole numbers that will multiply to make 12.

2. Finding Factors:

   • Demonstrate how to find factors for a different number, like 30.
   • Ask students to help identify the factors: 1, 2, 3, 5, 6, 10, 15, 30.

3. Practice Finding Factors:

   • Ask students to find factors for a number selected at random from 1 to 100 and share their answers with a partner.

---

Guided Practice (5 Minutes)

1. In-Pairs Activity:

   • In pairs, have students roll a pair of dice.
   • The sum of the dice will be the number they work with.
   • Each pair will find all the factors and create a list of factor pairs on chart paper.

2. Sharing Findings:

   • After a few minutes, ask pairs to share their findings and explain their reasoning to the class.

---

Independent Practice (5 Minutes)

• Distribute worksheets with a set of numbers.
• Have students find factors and complete the factor pairs for 5 different numbers between 1 and 100 on their own.

---

Closing (5 Minutes)

1. Review: Reinforce what factors are and how to find them.
2. Discussion: Ask the class why it is important to understand factors and multiples in math and real-life situations.
3. Exit Ticket: Each student writes one number between 1-100 and lists its factors before leaving the class.

---

Assessment

• Monitor students during the guided and independent practice to assess their understanding.
• Collect the worksheets to evaluate their ability to identify factors and factor pairs.

---

Extensions

• For advanced students, introduce the concept of prime and composite numbers.
• Use technology to engage students with interactive factor and multiple games.
