On a programme I watched the class teacher gave each child 3 coloured cups (red, yellow, green) and during the lesson the children changed the order of the cups depending on how they were feeling about the work (they were stacked up on the edge of the desk). Green- I understand and don't need help.Yellow- I'm struggling/could use help. Red- I need immediate assistance. This worked really well for the KS3 children (Yr8) in the programme. The teacher could see who needed help and go straight to them, however their work was almost always individual and the teacher didn't work with a group herself. I'm a student teacher and was considering trying to implement it in my Yr4 class. Any advice on this? Is it too fussy for children so young? Is it too disruptive? I've been told to stay sitting with the group I planned to sit with, dissuade children coming to me to ask something and to not get distracted from my group by other groups. But if I see a child's cup on red I'm obviously going to want to work with them otherwise the whole exercise would be moot...help!
