Lesson Plan: Finding Rates with Fractions

Grade: 7

Subject: Mathematics

Duration: 60 minutes

Objective: Students will be able to find rates when one or both quantities are fractions.

Materials: - Whiteboard or blackboard - Markers or chalk - Worksheets (links provided below) - Video resources (links provided below)

Introduction (5 minutes): 1. Begin the lesson by asking students if they know what a rate is. Allow a few students to share their answers. 2. Explain that a rate is a comparison between two quantities with different units. 3. Give an example of a rate, such as “The car traveled 60 miles in 2 hours. What is the rate of the car’s speed?”

Lesson Outline:

I. Understanding Rates with Fractions (10 minutes) A. Explain that rates can involve fractions as well. B. Write a simple rate on the board, such as “1/2 cup of sugar in 3/4 cups of flour.” Ask students to identify the two quantities being compared. C. Discuss how to interpret the rate and its meaning in real-life situations.

II. Finding Rates with One Fraction (15 minutes) A. Introduce the concept of finding rates when one quantity is a fraction. B. Provide examples on the board, such as “1/3 of a pizza was eaten in 1/2 hour.” Ask students to find the rate. C. Guide students through the steps of finding the rate by dividing the fraction quantities. D. Practice finding rates with one fraction using additional examples on the board.

III. Finding Rates with Two Fractions (15 minutes) A. Introduce the concept of finding rates when both quantities are fractions. B. Provide examples on the board, such as “2/3 of a tank was filled in 3/4 hours.” Ask students to find the rate. C. Guide students through the steps of finding the rate by dividing the fraction quantities. D. Practice finding rates with two fractions using additional examples on the board.

Questioning and Assessment (10 minutes): 1. Ask students to solve a few rate problems independently. 2. Circulate the classroom to observe students’ understanding and provide assistance as needed. 3. Use questioning techniques to assess students’ comprehension, such as: - How do you interpret a rate with fractions? - What steps do you follow to find a rate when one or both quantities are fractions? - Can you explain the meaning of the rate in a real-life context?

Differentiation: 1. For students who need additional support, provide extra practice problems with simpler fractions. 2. For students who grasp the concept quickly, challenge them with more complex rate problems involving mixed numbers or decimals.

Plenary (5 minutes): 1. Summarize the key points of the lesson, emphasizing the steps to find rates with fractions. 2. Ask a few students to share their answers to the independent practice problems. 3. Encourage students to ask any remaining questions or seek clarification on any concepts they found challenging.
