Now try this_ - Ian McDonald

The emphasis throughout is on relevance, realistic context and investigative work.;The "Blue Book" is an introductory book and covers topics that students will have come across in the lower school and prepares students for foundation level. The "Yellow Book" and the "Red Book" provide a parallel course for general and intermediate level students. The content of the course is divided between the two books. This allows for flexibility and economy of use. The books can be studied in any order. The "Green Book" is for credit level and those students who will do the higher level GCSE. It is a natural progression forom the intermediate level course.;The material introduces new concepts, developing and consolidating through worked examples and exercises. Students can work through the units on their own as cues are provided for teacher intervention. "Now Try This" involves activities that are investigative but do not require the collection of supplementary data, so are manageable in the classroom.;Each unit also contains an introductory problem which illustrates the need for the techniques being introduced, key questions to assess competence, answers to all questions and associated revision/homework units containing reminder facts and revision exercises. The teacher's book includes content and syllabus notes, advice on relevant software, solutions to investigations and key questions and their answers.
