Year 1 Mathematics Lesson Plan: Introduction to Basic Fractions (1/2)

Lesson Overview

This lesson plan is designed for Year 1 students in New Zealand, focusing on introducing the concept of basic fractions starting with 1/2. The session is planned to be interactive, catering to a small group setting of 4 students. The lesson includes extensions for students who are already familiar and confident with the topic.

Curriculum Alignment

This lesson aligns with the New Zealand Curriculum, specifically:

• Learning Area: Mathematics and Statistics
• Strand: Number and Algebra
• Level: Level 1 (Years 1-3)
• Achievement Objective: Students will be able to equipartition an object into equal parts and understand simple fractions as equal parts of a whole.

Lesson Details

• Subject: Mathematics
• Topic: Introduction to Basic Fractions (1/2)
• Year Level: Year 1
• Duration: 15 minutes
• Class Size: 4 students

Learning Objectives

By the end of this session, students will be able to:

1. Understand the concept of halves.
2. Identify and create halves in different physical objects.
3. Articulate the meaning of the fraction 1/2.

Resources Needed

• Paper sheets (several)
• Safety scissors
• Objects for partitioning (e.g., apples, oranges, small sandwich)
• Fraction circles/flashcards showing 1/2
• Worksheets for practising identifying and colouring 1/2
• Whiteboard and markers

Lesson Plan

Warm-up (3 minutes)

• Activity: Quick discussion on dividing things into equal parts. The teacher will show a biscuit and ask how it can be shared between two friends equally.
• Purpose: To engage students and link the lesson to familiar situations.

Introduction to Fractions (3 minutes)

• Activity: Introduction of the term "half" and the fraction symbol 1/2. Explore its meaning through visual aids (e.g., fraction circles).
• Purpose: To provide students with an understanding of fractional language and symbols.

Interactive Activity (6 minutes)

• Activity: Interactive "Fold and Cut" session. Students are given a paper sheet. They will fold the paper into two equal parts and cut along the fold line to make two equal pieces.
• Purpose: To physically engage students in the concept of creating halves practically.
• Extension: For quick learners, explore folding the halves into quarters briefly after performing initial task.

Group Discussion and Recap (2 minutes)

• Activity: Discuss what students did and observed during the "Fold and Cut" activity. Emphasise the two parts are equal.
• Purpose: Reinforce learning and clarify any misconceptions.

Conclusion and Worksheet Task (1 minute)

• Activity: Hand out worksheets with various objects drawn. Students are asked to colour in 1/2 of each object.
• Purpose: To provide students with an opportunity to apply their new knowledge and assess their understanding.
• Extension Activity: For students needing more, provide objects with quarters shaded, challenging them to identify halves versus quarters.

Assessment

• Observe students as they engage in the cutting activity and complete their worksheets. Check whether students can successfully identify and make halves of different objects.
• Discuss with students individually to ensure they understand the concept of 1/2.

Reflection

End the lesson with a brief reflection:

• What did we learn today about fractions?
• How might we use this knowledge in real life?

Encourage students to look at objects around the home and consider how they might be divided into halves or other fractions.
