My Take
I use this every lesson, I like how I can have data at a glance about each student and that it is an easy way for me to recognise achievement and share that with parents.
How I Use It
I used this last year for my 7,8&9 classes - initially just the seating charts. I would display them on the whiteboard so that students would know where I would want them to sit in that lesson. It was my classes that actually encouraged me to start using the behaviour management component - which I use mainly for recognising achievement in my lessons.
