### 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.
