Maths Mastery Reasoning: Teacher Resources KS1 contains a wealth of practical ideas and photocopiable resources to promote reasoning using precise mathematical vocabulary and stem sentences. It will enable teachers to explicitly teach children how to reason so they can answer questions such as: Which skills do I need to complete the task? How can I explain my thinking? What vocabulary do I need to use? Covering all areas of the primary maths curriculum including place value, fractions and the four operations, each photocopiable activity enables pupils to practise key skills and make links to the maths they are using. Many of the activities can be completed using a concrete, pictorial and abstract (CPA) approach to teaching maths. Written by John Bee, NCETM Primary Mastery Specialist, this must-have resource is ideal for teachers just starting on the maths mastery journey or for more experienced teachers who need some fresh input and ideas. This unique book will engage pupils in lively debate when they hypothesise, agree, criticise and prove their learning around key mathematical concepts. A companion book for Key Stage 2 is also available.
