No matter how well you plan out the day, there are going to be times when you have to quickly and creatively fill up a five- to ten-minute gap in the schedule. That's where "sponge activities" come into play. Sponge activities soak up those in-between-minutes with easy-to-implement challenges that motivate students to stretch their minds in new directions. Most of the activities can be done independently, in teams, or as a class, depending on your needs. As the year continues, you'll develop many sponge activities of your own based on the lessons you are teaching. Until then, these ideas will keep students involved and learning when there are unexpected minutes to fill.
