Within each of these lessons, teachers follow the Concrete-Pictorial-Abstract (CPA) approach in line with our school’s Calculation Policy. Each mathematical concept is introduced with concrete resources to allow all pupils to access new learning. We use many models in maths to explain key areas of learning: ten frames, Base 10, number lines, part-part-whole and bar model. These are used to support our children in the concrete and pictorial aspects of lessons before they are able to reach the abstract level of understanding. Children are familiar with these resources and can access them independently where needed.
