Power Maths is a maths toolkit that uses the 'mastery' approach to teaching maths. This means that children look at a concept in a range of different ways, in order to fully and deeply understand it. This included working with talk partners and discussing a range of ideas and the use of visual and concrete manipulatives. Each lesson begins with a problem solving activity to engage the children and get them discussing mathematical concepts within a meaningful context. Throughout the lesson there is a balance of teacher and pupil discussion before children move on to 'practice' what they have learnt and then extend and consolidate this by moving onto challenges and deepening and strengthening activities.
