Written Calculation comprises six Pupil Books, six Answer Books, a Teacher's Guide and a Teacher's Resource Book and uses methods recommended in the National Curriculum. Designed for use at Key Stage 2, each Pupil Book uses 18 carefully structured steps to guide the learner towards full mastery of each written method, supporting them in their national tests and other areas of the National Curriculum. Written Calculation also helps pupils develop confidence and fluency in their learning by practising and embedding place value, number facts and problem solving skills. The importance of estimating and checking answers is also emphasised. Written Calculation: Subtraction Answers accompanies the corresponding Pupil Book and provides correct answers to all questions. Each of the six Answer Books begins with a useful reminder of the key principles in the Pupil Book and includes a card cover, making it a durable resource, suitable for frequent reference. Answers are clearly laid out in the format of a correctly completed Pupil Book in order to make marking quick and simple. Scores may be recorded for each pupil in a class/set on the Group record sheet, located at the back of this Answer Book. The accompanying Teacher's Guide provides useful notes and ideas for planning lessons, enabling a whole-school approach. Detailed Teaching notes outline clear learning objectives and a Summary of the steps for each Pupil Book is included. Photocopiable Assessment resources allow you to monitor and assess pupils' progress. Supplementary Further practice and Problem solving questions can be found in the Teacher's Resource Book. These photocopiable resources may be used for further practice, assessment, revision or homework and correspond to the steps covered in each of the Pupil Books.
