With our state testing now being timed, I have really started implementing more timed activities in the room. I am blessed to have a SMARTboard and projector, so I always have something going on the board. I found these really neat online timers.
Some of them are fun when "time is up". Some will get annoying, but the kids will know they have run out of time! I think I will vary them up.
You can still use it even if you don't have a projector. They are online timers, so all you need is the internet!
