I set it for five minutes of quiet reading, then built up the time by a minute each day - up to 15 minutes - but didn't tell the children I was doing this. I told them that while the timer is going I wanted to be able to hear it ticking or I would start it again. It has been so successful that other teachers now use the idea. I also use it if the class gets too noisy at other times. Pupils really like the timer and think it is fun.
