Learning Objectives

By the end of this lesson:

• Students will be able to identify and define fractions as equal parts of a whole.
• Students will demonstrate an understanding of how to compare, add, and subtract fractions with like denominators.
• Students will apply their learning in a creative activity to enhance their understanding of fraction concepts.

Materials Needed

• Fraction cards with visual representations (1/2, 1/3, 2/4, etc.)
• Whiteboard and markers
• Paper cut into circular and rectangular shapes for fraction modeling
• A variety of snack items (optional for activity): crackers, chocolate bars, or fruit pieces to show real-life fractions
• Pre-prepared worksheets with fraction problems
• Sticky notes or small index cards for interactive activity

Lesson Structure

1. Introduction (10 Minutes)

Objective: Activate prior knowledge and engage students.

Step 1: Warm-Up Question (3-5 Minutes)

Begin by writing the question on the board:
"If I eat 2 slices of a pizza with 8 total slices, what fraction of the pizza did I eat?"

• Allow students to think-pair-share their answers. Highlight their ideas about numerator (the part) and denominator (the total).

Step 2: Brief Overview of Fractions (5 Minutes)

Explain fractions clearly:

• A fraction is a way of showing part of a whole.
• The numerator is the top number (the parts you’re talking about).
• The denominator is the bottom number (the total number of parts).
  Give age-appropriate examples:
• 1/2 of a sandwich is one-half.
• 2/5 of a basketball team means 2 out of 5 players.

Illustrate real-life uses of fractions (e.g., pizza, classroom groups, measuring ingredients in cooking).

2. Core Instruction (20 Minutes)

Objective: Teach students about comparing, adding, and subtracting like fractions.

Step 1: Visual Explanation (10 Minutes)

Use circular paper cutouts or fraction cards to explain:

1. Equal Parts: Show a circle divided into halves, thirds, and quarters.
   • Ask: “Which is bigger, 1/2 or 1/4? Why?”
2. Adding Fractions with Like Denominators:
   • If you have 1/4 of a pizza and I give you another 1/4, how much pizza do you have in total?
   • Demonstrate: 1/4 + 1/4 = 2/4 (then simplify to 1/2).
3. Subtracting Fractions with Like Denominators:
   • If you have 3/4 of a bar of chocolate and eat 1/4, how much do you have left?
   • Demonstrate: 3/4 – 1/4 = 2/4 (then simplify to 1/2).

Step 2: Group Work Practice (10 Minutes)

Break students into 8 groups (5 students per group). Provide each group with fraction cards and a whiteboard. Assign the following problems:

• Compare fractions using >, <, or = (e.g., 1/2 ___ 2/4).
• Add fractions with like denominators (e.g., 2/8 + 3/8). Simplify answers.

Walk around the class, observe, and ask guiding questions as they work together.

3. Fraction Activity (20 Minutes)

Objective: Allow students to apply their understanding in a creative and interactive way.

Activity: "Fraction Feast"

1. Preparation (2 Minutes)
   Provide each group with small snack items (e.g., a chocolate bar, crackers, or fruit) and task cards with specific fraction problems.

2. Instructions (3 Minutes)

   • Each group will divide the snack into equal parts, creating as many fractional pieces as possible (e.g., split a chocolate bar into 10 equal pieces, with each piece being 1/10).
   • Solve their task problems using the fractional snack pieces. For example, Combine 2/10 and 3/10 of a chocolate bar to make what fraction?

3. Execution (15 Minutes)
   Groups will discuss and solve problems while physically manipulating their snack items to see fractions in action. Groups will record their work and answers on sticky notes or index cards.

4. Closing and Reflection (10 Minutes)

1. Review Questions (5 Minutes)

   • What is a fraction? Give an example.
   • How do we add fractions with the same denominator?
   • What real-life situations use fractions?

2. Student Reflection (3-5 Minutes)
   Provide students with a quick reflection prompt: Write on a sticky note one thing you learned about fractions today., then stick it on the classroom “Math Wall.”

3. Take-Home Challenge
   Ask students to find one example of fractions around their home (e.g., measuring cups in the kitchen) and bring their example to the next class.

Differentiation Strategies

• For struggling learners: Use more visual aids (e.g., fraction bars or digital fraction manipulatives on a tablet). Pair students with stronger peers during group activities.
• For advanced learners: Provide extension problems involving mixed numbers and improper fractions to challenge their learning.

---

Assessment

• Observation during group work and activity (Are students demonstrating understanding?)
• Correctness of sticky note answers.
• Evaluate students’ participation in review questions and reflection.

Teacher's Note

Fractions are a foundational skill in Grade 5. Keep the tone positive and make learning fun using the activity. Real-world connections with snacks help bridge abstract math concepts with hands-on learning. Make sure no student feels left out or overwhelmed by ensuring groups are balanced with varying abilities.
