Time is usually introduced to preschoolers as a sequence of events. So in our classroom, we have a schedule that visually illustrates the child's sequence of activities at preschool. I have created a card for each part of our session: putting their name on the board when they arrive, free play, tidy up time, cirle time, work time, snack time, outdoor play etc... Each time we change our activities, a child is designated to pin the appropriate card on our colourful magnetic board. Everytime it is time to move on to another sequence in our schedule, I ring a little bell and ask the children "what time is it?". They always know what comes next! A child's capacity to learn about time increases as she/he becomes aware of how events recurring at specific times structure her/his days.
