Lesson Plan for Year 3 - Mathematics - Introduction to Fractions

**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. --- **End of Lesson**
