The workbooks are set out in a fun and easy-to-use format. Each concept is covered by step-by-step worksheets which ensure maximum understandingand minimum errors. The multiple-choice section shows up silly (and not so silly!) mistakes in an amusing and appealing way. There is also a 'm ock' Test Paper at the end of each book which is already completed, in which students must try to find all the mistakes! This teaches valuable proof-reading skills and provides a great way to help students understandhow to check their work.
