The topic of discussion this week is warning systems – so very much a behaviour-based episode rather than a maths one.  
Matt and Femi cover a fair bit of ground: from classrooms with names written on the board and hundreds of warnings being issued each day through to classrooms with no warnings and students absorbed in their work.  And from supporting colleagues with behaviour issues through to the prospect of creating a school-wide culture around behaviour that leaves deleterious learning behaviours at the school gates.
