Number Lines

Linear models of number are very important as they support the development of an informal internal representation of number magnitude, called the mental number line. Different models are best suited to the teaching of different skills and understandings at different levels. This book is designed to help teachers make the best use of number tracks, number grids, and both empty and calibrated number lines.

Reasoning with Rods: Developing Mathematics Concepts with Coloured Rods

Linked to the Australian Curriculum

Reasoning with rods
Dr Paul Swan

Coloured rods (often known as Cuisenaire rods) are a versatile and readily available manipulative which model our number system. The activities and tasks in this book can be used to develop a number of mathematical concepts: addition and subtraction using a range of efficient strategies, factors and multiples, patterns, fractions, area and if–then thinking. There are games, riddles and puzzles.

This volume also has a comprehensive teacher guide to the different kinds of operations that can be modelled using the rods, such as addition (and its commutative and associative properties), subtraction, multiplication using repeated addition and arrays, and division models of sharing and repeated subtraction.
