Upper Primary Mathematics Fractions - Commonwealth of Learning

Module 2
Fractions
Introduction to the Module
This module is about teaching fractional numbers, fractional numerals, and
their manipulation. Algorithms for manipulating fractional numbers and
numerals only became feasible with the advent of the Hindu-Arabic numeral
system. Just try to add one-third plus one-fourth using Roman numerals!
Learning these fraction algorithms, and the reasoning behind them, is among
the most important tasks in Upper Primary Mathematics.
Aim of the Module
The aim of the series of modules is to attempt to guide teachers to make
teaching of mathematics simple, enjoyable, and understandable. In particular,
this module explores ways to consolidate the manipulation of fractions in the
early stages of learning. It also explores interesting and practical ways of
using fractional numbers and their operations.
Structure of the Module
There are six units in this module. Unit 1 is a review of common fractions. Unit
2 discusses the two operations of addition and subtraction. In Unit 3 we look
at multiplication and division operations. Units 4 through 6 extend the basic
concepts to decimals, ratios, and percentages. The module offers a series of
unit and practice activities to help you consolidate the content and teaching
strategies. The self-assessment exercises will help you evaluate your methods.
Objectives of the Module
The specific objectives of the module are to:
• help teachers consolidate the basic concepts of fractional numbers
• explore interesting and practical ways of teaching fractional numbers
• introduce teachers to problem-solving skills
