I thought I had better search my own wardrobe, but had nothing eccentric that could be turned into a fairytale costume. All I found was an old hippie-ish woolly jumper from my university days with an enormous blue flower printed on the front and a smaller one on the back.
This gave me an idea, so the following morning, earlier than usual, I borrowed my four-year-old son's face painting kit and carefully designed plants, flowers and some silver bells on my face. Then I drove off to school, aware that other drivers were probably looking at me curiously, but I was nonetheless happy to arrive at school looking like a possible Mary, Mary, Quite Contrary.
When my Year 5s entered the classroom and saw how I looked they were unusually quiet, intrigued by whom I might be. I enjoyed guessing who they were and moved on surprisingly swiftly to the day's work, without all the usual "look and listen" gestures I normally have to make. Perhaps it was that I was more relaxed hiding behind someone else's identity. Anyway, the next day came and I remember thinking, "Who should I be today?"
Worst: I was keen to make French lessons fun for Years 1 and 2, so I thought it a good idea to introduce food. Each would make their own pizza and take it home to cook.
I had it all carefully planned out. Ingredients were laid out for demonstration on my big table: flour, water, a measuring container, olives and tomato sauce. Their tables had each a thin plastic sheet with the right amount of flour and water in a glass. As Year 1 came in, they sat down on the carpet and listened to the ingredients and instructions, all in French.
Then in pairs, they made their pizzas, mixing flour and water into a ball, flattening it and adding their choice of ingredients. It was all a bit messy, but they took their pizzas home afterwards and I left, happy that they seemed to have enjoyed this practical lesson.
But I failed to notice all the flour stuck on the carpet. Worse, it was the deputy head who alerted me to it. He called me in to tell me he had been trying to clean the mess I had left. He had been at it for a long time and had other important things to do. I was embarrassed and disappointed - he cleaned my mess and all I had cared about was my pupils enjoying themselves and learning some French. Soon after, a new carpet was bought for my classroom
