In DS's year 3 class children who have grasped something, particularly in maths, are then paired with a child who hasn't grasped it to be a 'teacher'. What do others think about this? I think it could get demoralising for those children who are never a teacher and I think the children who have grasped it should be allowed to move on to new things. It seems like lazy teaching to me but I'd welcome other's views.
