Teachers strive to design lessons in which the pupils are carefully guided, step by step, through Mathematical fluency, reasoning opportunities and are given problems to solve. Lessons include rehearsal and automatic recall of facts. The lessons incorporate the 5 Big Ideas of teaching for Mastery. Particular attention is paid to developing conceptual understanding in tandem with procedural competency. Children are challenged to explain their reasoning, evaluate their own (and the work of others), model their ideas and invent their own questions. Presentations are clear, concise and coherent. The creation of lesson design incorporates material from the National Curriculum, NCETM resources and White Rose Maths.  All children between Year 1 and 6 have White Rose Maths booklets which are used in lessons.
