Do you lose track of time during groups? Do you students need help with time management? Then this is the thing for you!!!
This is a powerpoint presentation that I use generally during math stations, but it can really be used in any subject.
The presentation automatically counts down 15 minutes, with audio at each minute (it sounds like a page turning), with build in trasition time, and a warning to the students that groups will be switching soon. It is a great tool for them to see how much time they have left at a station. It also helps them manage their time, as well as yours!
It automatically counts down for 4-15 minute groups. It could be modified for your specific needs, but a great, usable, template is already there for you!
