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.

Navigating through Reasoning and Proof
Maurice J. Burke, Jennifer Luebeck, Tami S. Martin, Sharon M. McCrone, Anthony V. Piccolino, Kate J. Riley

Expanding from ‘reasoning to obtain solutions’ to ‘reasoning to justify ideas and validate results’ is a significant development for the student of mathematics. Activities highlight the cycle of exploration, conjecture and justification. Supported by blackline masters, the activities build on and extend problem solving and reasoning to include proof; through Number, Algebra, Geometry, Data Analysis and Probability and Measurement. The book is accompanied by a CD-ROM which includes further reading for teachers, files for the blackline masters, and computer applications for students to use in their investigations.
