Written Calculation: Subtraction

Written Calculation provides simple instruction, worked examples and structured practice in the aspects of written calculation that pupils need to master by the end of Key Stage 2. The series 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. Online answers are also available on the Schofield & Sims website.

Each Pupil Book uses 18 carefully structured steps of learning to guide the learner towards full mastery of each written method. The series 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 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.
