Build time sense into the schedule by asking learners to predict what can happen in a certain amount of time: We have 20 minutes before outdoor time. What can you get done? Everyone makes a prediction, for instance, how many rounds of a card game they’ll play or how many origami cranes they can make. Then, stop part-way through the time period and ask if anyone wants to revise their predictions. [Activity is publicly available through a web crawler capture on]
