A very interesting question has been left in the comment section after my piece on false fatigue. "What should a teacher do during this time? I have only substituted in a classroom as I am still training, but what I noticed was engaging in imaginary play and misusing materials and furniture, so how do you deal with that without over managing?"
So, if the imaginary play is not annoying or offending other children and the materials are not being misused, I would stand back and observe what is actually taking place. Is the child exploring the materials and making discoveries within that imaginary play? Does the child abandon imaginary play after a few minutes and become deeply focussed on the work? Is this play the child's way of partaking in false fatigue – is this her way of preparing for the next stage of work? Observation will answer any of those questions and will dictate what, if any, action is needed by the teacher.
Hope this helps.
