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 leads pupils through the necessary steps for mastering the column method of subtraction. Pupils beginning this book should have an understanding of the value of digits in two- and three-digit numbers, experience of adding and subtracting single-digit numbers and know their subtraction number bonds to 20.
Each of the 18 steps features the following sections: What to do – detailed explanations and a worked example; Now you try – questions that are similar to those in the worked example; More practice – questions that are a little more difficult and provide less support than those in Now you try; Problem solving – word problems; Self-evaluation rating – to help identify pupils who may be struggling with the step. Three Check-up tests and a Final test enable you to monitor pupils’ progress and quickly convert scores to percentages. These scores may later be recorded on the Group record sheet. 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.
