**Lesson Plan: Introduction to Fractions**
**Grade Level:** Year 3
**Subject:** Mathematics
**Duration:** 60 minutes
**Topic:** Introduction to Fractions
---
### Objectives
- Students will understand what fractions are.
- Students will be able to identify and represent fractions such as 1/2, 1/3, and 1/4.
- Students will understand how to divide objects into equal parts.
### Materials
- Whiteboard and markers
- Fraction circles or fraction strips
- Paper, pencils, and crayons
- Interactive fraction games or apps (optional)
- Printed worksheets on fractions
### Common Core Standards
- CCSS.MATH.CONTENT.3.NF.A.1: Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
- CCSS.MATH.CONTENT.3.NF.A.2: Understand a fraction as a number on the number line; represent fractions on a number line diagram.
### Procedure
#### Introduction (10 minutes)
1. **Greeting and Warm-Up**
- Start with a quick warm-up exercise asking students about their favorite foods that can be divided into parts (pizza, chocolate bars, etc.).
- Discuss the words “part” and “whole” using real-life examples.
2. **Objective Sharing**
- Briefly explain that today’s lesson will be about fractions, which are used to describe parts of a whole.
#### Direct Instruction (15 minutes)
1. **Introduction to Fractions**
- Use the whiteboard to draw a whole shape (e.g., a circle) and divide it into two equal parts. Shade one part and explain that this represents the fraction 1/2.
- Repeat this step with other simple fractions such as 1/3 and 1/4 using different shapes.
2. **Using Manipulatives**
- Introduce fraction circles or strips to visually represent fractions.
- Show how these can be divided and labeled with fractions like 1/2, 1/3, and 1/4.
3. **Discussion**
- Engage students by asking them to predict what fraction they get if a shape is divided into three equal parts and one part is shaded.
#### Guided Practice (15 minutes)
1. **Hands-On Activity**
- Distribute paper, pencils, and crayons.
- Ask students to draw and color their own shapes (circles, squares) and divide them into halves, thirds, and quarters, shading one part of each.
2. **Group Work**
- Divide students into small groups.
- Provide each group with a set of fraction circles or strips and a worksheet.
- Have them practice identifying and labeling fractions.
#### Independent Practice (10 minutes)
1. **Worksheet Completion**
- Give students a worksheet with various shapes divided into parts.
- Ask students to write down the fraction that represents the shaded part.
#### Assessment and Closure (10 minutes)
1. **Review Questions**
- Ask students some review questions like:
- "What fraction do we call two equal parts of a whole?"
- "If one part of a circle divided into three is shaded, what fraction is shaded?"
2. **Exit Ticket**
- As an exit ticket, have each student draw a shape, divide it into parts, and write the fraction for the shaded part.
### Extensions
- Students who finish early can use interactive fraction games or apps to reinforce the concept.
- Introduce more complex fractions such as 2/3 or 3/4 for advanced learners.
### Homework
- Assign a worksheet where students draw objects divided into different fractions to practice at home.
### Reflection
- After the lesson, ask students what they found easy or difficult about fractions.
- Use their feedback to adjust future lessons and provide targeted support where necessary.
