Foreword Number grids are a cheap and versatile teaching aid that may be used: • to develop number skills; • as a means of examining number patterns; and • as a source of investigation. The majority of activities in Number Grids are based on the 1–100 number grid. Many commercial number grids are based on the 1–100 number grid and the activities in this book may be used in conjunction with these products. It should be noted, however, that the activities may be used with other number grids such as the 0–99 number grid. Different number grids may be used to extend the activities contained in this book. Section 1 contains a variety of different grids that may be used for this purpose. Instructions are provided so that teachers and, better still, students can make their own number grids. Number grids may be used on a regular basis to assist in the development of mental computation skills. The possible uses of number grids are unlimited if the students are given the chance to explore. Dedicated to Geoff White who suggested many improvements to the manuscript and helped me to think outside the square.
