I was recently tasked with delivering a staff meeting about good practice when teaching Maths. It went down quite well with the other staff at my school so thought I'd upload my accompanying SMART on here. I covered concepts such as challenge, reasoning, real-life and practical opportunities etc. I was also able to point people in the direction of useful documents to aid with the planning and delivery of Maths, especially in relation to achieving greater depth.
