I brought this book for my 9 year old son, just entering year 5. It is not like other 'help' books that I have purchased in the past as each segment is over 2 pages, with the first page being a description of the subject matter and then the opposite page is broke down into sections, of expected level and then 'aiming higher' questions later on on the page. If you are unsure of the answers, then there is a pull out answer booklet in the centre.
Using these guides, based on the curriculum, means that parents can have confidence that they are supporting the work done in school. Topics are divided into easily manageable chunks, with clear explanations and questions to test learning. The key facts and language boxes make the background to the topic clear and are an excellent support to learning. Answers are in a pull-out booklet which is very practical and makes cross-reference easy.
