National Numeracy Strategy (NNS) for Key Stage 3 will be introduced into Secondary Schools in September 2001. The NNS document: Framework for Teaching Mathematics in Years 7 to 9, is based on the National Curriculum, but offers a very different interpretation of some of the expected learning outcomes for year 7 to 9. This practical book, interprets and explains the document for busy practitioners, spells out the expectations of the framework and offers guidance on how to fulfil these, describes and explains the types of teaching methods for maximising students' learning, and includes many practical ideas for classroom activities within the framework of the NNS.
