Lesson Plan: Fun with Fractions! (Grade 6 or 7)
Subject: Mathematics
Topic: Introduction to Fractions
Time Allotment: 60 minutes
Learning Objectives: By the end of this lesson, students will be able to:
- Define a fraction as part of a whole.
- Identify the numerator and denominator of a fraction and explain their meaning.
- Recognize and represent simple fractions visually.
- Understand the concept of equivalent fractions (introductory level).
Materials:
- Whiteboard or projector
- Markers or pens
- Pre-cut paper circles or squares (various colors)
- Markers or crayons for students
- Fraction strips (optional, can be made from paper)
- Worksheet with fraction identification and representation exercises
- Real-life examples (e.g., a pizza cut into slices, a chocolate bar divided into sections)
Lesson Procedure:
1. Engage (10 minutes): Real-Life Fractions
- Teacher: "Has anyone ever shared a pizza with friends? Or maybe a cookie? When you do that, you're actually using fractions!"
- Show a real-life example like a pizza box with slices or a chocolate bar with breakable sections.
- Teacher: "Imagine this pizza has 8 slices. If you eat 2 slices, how much of the pizza did you eat?" (Encourage student responses and guide them towards the idea of "2 out of 8").
- Briefly introduce the idea that fractions help us describe parts of a whole.
2. Explore (15 minutes): What is a Fraction?
- Teacher: "Let's dive deeper into what a fraction actually is."
- Draw a circle on the board. Divide it into two equal parts. Shade one part.
- Teacher: "This shape is the 'whole'. We've divided it into 2 equal parts. The shaded part represents a 'fraction' of the whole."

Subject: Mathematics
Topic: Understanding Fractions
Grade Level: 7 (Approximately 12 years old)
Time Allotment: 60 minutes
Learning Objectives:
Students will define a fraction and identify its parts (numerator and denominator).
Students will represent fractions visually using diagrams.
Students will understand the concept of equivalent fractions.
Students will compare and order fractions with like and unlike denominators.
Materials:
Whiteboard or projector
Markers or pens
Fraction manipulatives (fraction bars, circles, or tiles)
Paper and pencils
Worksheet with fraction exercises
Real-life examples (pictures of divided objects, food, etc.)
Lesson Procedure:
1. Introduction (10 minutes): What is a Fraction?
Begin by asking students about times they've had to share something equally.
"Has anyone ever had to share a pizza, a cake, or a set of toys with friends or family?"
"How did you make sure everyone got a fair share?"
Introduce the concept of fractions as a way to represent parts of a whole.
Lecture:
"A fraction is a way of representing a part of a whole or, more generally, any number of equal parts. It consists of two numbers separated by a line."
"The number on the bottom is called the denominator. It tells you how many equal parts the whole is divided into."
"The number on the top is called the numerator. It tells you how many of those equal parts we are considering."
Draw a circle on the board and divide it into 4 equal parts. Shade 3 of them.
"In this example, the whole circle is divided into 4 equal parts, so the denominator is 4. We've shaded 3 of those parts, so the numerator is 3. The fraction representing the shaded part is 3/4."
Show visuals of various fractions (1/2, 1/3, 2/3, 1/4, 3/4, etc.) using different shapes (circles, squares, rectangles).
2. Visual Representation of Fractions (15 minutes): Hands-On Activity
Distribute fraction manipulatives (fraction bars, circles, or tiles) to each student or group.
Have students represent different fractions using the manipulatives.
"Show me 1/2 using your fraction manipulatives."
"Can you represent 2/3?"
"Use your manipulatives to show 3/4 of a rectangle."
Draw different shapes on the board, divide them into equal parts, and shade some parts. Ask students to write the fraction represented by the shaded area.
Have students draw their own shapes, divide them into equal parts, shade some parts, and write the corresponding fractions.
3. Equivalent Fractions (15 minutes): Finding the Same Value
Introduce the concept of equivalent fractions: fractions that have the same value but different numerators and denominators.
Lecture:
"Equivalent fractions represent the same portion of the whole. For example, 1/2 is equivalent to 2/4, 3/6, 4/8, and so on."
"To find equivalent fractions, you can multiply or divide both the numerator and the denominator by the same non-zero number."
Use visuals to demonstrate equivalent fractions:
Draw two rectangles of the same size. Divide one into 2 equal parts and shade 1 part (1/2). Divide the other into 4 equal parts and shade 2 parts (2/4). Show that the shaded areas are the same.
Use fraction bars to show that 1/2 is equal to 2/4, 3/6, and so on.
Practice finding equivalent fractions:
"What fraction is equivalent to 2/3 with a denominator of 6?" (Answer: 4/6)
"Find a fraction equivalent to 3/4 with a numerator of 9." (Answer: 9/12)
4. Comparing and Ordering Fractions (15 minutes): Which is Bigger?
Explain how to compare fractions with like denominators:
Lecture: "When fractions have the same denominator, you can compare them by looking at their numerators. The fraction with the larger numerator is the larger fraction."
Example: 3/5 > 1/5 because 3 is greater than 1.
Explain how to compare fractions with unlike denominators:
Lecture: "When fractions have different denominators, you need to find a common denominator before you can compare them."
Explain the concept of finding a common denominator (finding a common multiple of the denominators).
Example: To compare 1/2 and 1/3, find a common denominator (6). Convert 1/2 to 3/6 and 1/3 to 2/6. Now compare the numerators: 3/6 > 2/6, so 1/2 > 1/3.
Practice comparing and ordering fractions:
"Which is larger: 2/5 or 4/5?"
"Which is smaller: 1/3 or 1/4?"
"Order these fractions from least to greatest: 1/2, 3/4, 2/3."
5. Wrap-up and Assessment (5 minutes): Review and Check
Review the main points of the lesson:
What is a fraction?
What are the numerator and denominator?
What are equivalent fractions?
How do you compare fractions?
Distribute a short worksheet with practice problems on:
Identifying fractions from visual representations.
Finding equivalent fractions.
Comparing and ordering fractions.
Collect the worksheets to assess student understanding.
Differentiation:
For struggling learners: Provide extra support with fraction manipulatives. Use simpler fractions (1/2, 1/4, 1/3) and focus on visual representations.
For advanced learners: Introduce simplifying fractions and comparing fractions with larger denominators. Challenge them with more complex problems and real-world applications.
Visual Aids:
Use colored markers to represent different parts of a fraction.
Draw circles, squares, and rectangles divided into equal parts to represent fractions.
Use fraction bars or circles to demonstrate equivalent fractions.
Use number lines to compare and order fractions.
Show real-life examples of fractions (e.g., a pie cut into slices, a measuring cup with fraction markings).
