PERIOD 1 & 2: Introduction to Equivalent Fractions

PRESENTATION:

Step

Teacher’s Activity

Pupil’s Activity

Step 1 - Introduction

Introduces concept of equivalent fractions with simple examples.

Pupils listen and ask questions.

Step 2 - Explanation

Demonstrates using fraction strips and division.

Pupils observe and discuss.

Step 3 - Practice

Shows how to simplify fractions or multiply to generate equivalents.

Pupils practice and respond.

Step 4 - Note Taking

Teacher summarizes with examples on the board.

Pupils copy notes and practice.

NOTE ON BOARD:
• Equivalent fractions have the same value.
• Examples: 1/2 = 2/4 = 4/8
• To create equivalent fractions, multiply or divide both numerator and denominator by the same number.
