Lesson Plan: Understanding Division Through "The Doorbell Rang"

Grade Level: 3rd Grade Subject: Math Topic: Division (Equal Groups and Fair Shares) Duration: 45 minutes

Lesson Objective:

By the end of the lesson, students will be able to understand and solve division problems using equal groups and fair shares and apply this concept to real-life situations.

Materials/Resources:

· "The Doorbell Rang" by Pat Hutchins

· Counters, tiles, or small candies for hands-on activities

· "Division: Equal Groups and Fair Shares" worksheets (Math Mammoth)

· Online interactive activities (I-Ready, Khan Academy)

· Story problems from Math Playground

Lesson Procedures:

1. Warm-Up Activity (5-7 minutes):

Introduction to Division Terms (2-3 minutes):

· Briefly introduce the key terms that will be used throughout the lesson. You can display the terms on the board and explain them:

· Dividend: The number that is being divided.

· Divisor: The number by which the dividend is divided.

· Quotient: The result of the division.

· Equation: The mathematical expression showing the division (e.g., 12 ÷ 4 = 3).

· Worksheet Explanation (1-2 minutes):

· Hand out the Division Terms Worksheet to each student. This worksheet will include the following:

· Definitions of division terms (provided above).

· 7 problems where students will need to write the number in the correct space for a division equation.

· Encourage students to identify the dividend, divisor, and quotient before writing the equation.

Independent Work (2-3 minutes):

· Allow students to work on the worksheet individually. Walk around to provide support as needed.

Quick Review (1-2 minutes):

· After students complete the worksheet, review the answers as a class. Ask students to explain their reasoning for each division equation they wrote. Correct any misunderstandings and reinforce the connection between the word problem and the division equation.

2. Introduction to "The Doorbell Rang" (10 minutes):

· Read aloud the story “The Doorbell Rang” by Pat Hutchins. Emphasize the division aspect as the children in the story share cookies equally with each visitor.

· After reading, ask questions such as:

· “How many cookies did the children start with?”

· “How did the number of cookies change as more people came to the door?”

· “How did they divide the cookies equally?”

· Use these questions to make connections to division, highlighting the idea of equal groups.

3. Hands-On Activity (10-12 minutes):

· Activity Setup: Provide students with 12 counters (or candies/tiles). Ask them to divide them into equal groups based on different scenarios. Example:

· Divide 12 counters into 3 groups, 4 counters per group.

· Divide 12 counters into 4 groups, 3 counters per group.

· Divide 12 counters into 6 groups, 2 counters per group.

· Allow students to work in pairs or small groups, discussing their strategies and how they are making the groups equal.

4. Real-Life Connections (5-7 minutes):

· Present real-world scenarios for division:

· “Imagine you have 16 cookies and 4 friends. How can you share the cookies equally?”

· “You have 24 stickers and want to share them with 8 friends. How many stickers does each friend get?”

· Allow students time to solve these problems using counters or drawings, reinforcing the practical application of division in everyday life.

5. Collaborative Problem-Solving (5-7 minutes):

· Pair students together and give them a new division problem to solve:

· “You have 20 toys and want to divide them equally into 5 groups. How many toys does each group get?”

· Encourage discussion and sharing of strategies between students. Walk around and assist where needed, prompting them with questions like, "How can we check if our groups are equal?"

6. Independent Practice (5-7 minutes):

· Provide each student with the "Division: Equal Groups and Fair Shares" worksheet. Let them complete a set of problems independently, applying what they’ve learned.

· Include problems such as:

· "If you have 18 apples and share them between 3 baskets, how many apples are in each basket?"

· "If 15 students are divided into 5 groups, how many students are in each group?"

7. Conclusion and Reflection (5 minutes):

· Wrap-up the lesson by reviewing what division is and how students can use equal groups or fair shares to solve problems.

· Ask students to share their answers from the independent practice and reflect on the strategies they used to solve the problems.

· Assign a brief exit slip where students must explain in their own words how they would divide 12 items between 3 friends.

Assessment Opportunities:

· Formative: Observe students during group discussions and the hands-on activity to assess understanding of division concepts.

· Summative: Review student responses on the independent practice worksheet for accuracy and understanding.

· Exit Slip: Evaluate each student’s ability to explain the division process in their own words.

Differentiation:

· For students needing additional support: Provide smaller group instruction or additional practice with concrete objects.

· For students needing challenge: Provide higher numbers for division or introduce word problems with remainders.

Reflection:

· After the lesson, reflect on how well students understood the concept of division. Did they grasp the idea of equal groups? Were they able to apply the strategy in real-life scenarios? Based on student performance, adjust future lessons to provide more practice or challenge.
