  Numbers are the building blocks of all mathematical processes. This book looks at units, tens and hundreds, decimals, fractions, percentages and negative numbers. It explains how numbers are ordered and compared, and draws on everyday life for examples. The book starts by explaining how whole numbers up to one hundred are ordered, then goes on to look how numbers are made (in groups of tens, hundreds and thousands) and the concepts of greater than , less than and equal to . It shows how to make good estimates of numbers, then introduces more advanced concepts. Temperature is used to illustrate negative numbers, and fractions are shown as parts of pizza. Decimals are described in the context of money and measurements, and percentages as a way of comparing scores.
