This is a powerpoint version of our school calculation policy for Maths. It goes through addition, subtraction, multiplication and division giving an overview of the development of recording methods from Y1 upto Y6 for each one, with examples shown. Includes mark making, number lines, multiplication grids and formal methods. This was used for a presentation to parents in a calculations workshop and was very well received. Obviously it would need tweaking to reflect your specific calculations policy but it might save a lot of time compared to starting from scratch.
