This series is in direct response to the Williams Review which states that 'encouraging pupils to talk mathematically is a key component in any successful pedagogy on a whole-class basis, as a regular part of the daily mathematics lesson.' To initiate mathematical discussion, each activity in these books starts with a whiteboard stimulus - this could be simply a set of mental maths questions, which teachers discuss with pupils to establish strategies and techniques, or it could be a problem to solve, a pattern to continue, a set of shapes to discuss or a set of questions that the pupils have to work through in written form after the discussion. Some of the activities are deliberately short and others open-ended with thought-provoking questions, outlined in the Teachers' notes, encouraging interactivity between the pupil and teacher and from pupil to pupil. Each book features 30 activities with an introductory page showing Learning Objectives, Learning Outcomes and Success Criteria (i.e. how to make effective assessments of pupils' progress) followed by a page featuring a screenshot of the whiteboard with suggested questions, discussion points vocabulary and assessment pointers.
