In this book, children are taught the basics of solving simple linear equations, in a logical and methodical manner. The book is published with a CD of the worksheets to enable teachers to print them out and use them in class. This book concentrates on patterns in tables and encourages the children to start to look for what is the 'same' in their patterns. They will start to think algebraically and have fun developing their number work.
