Social Studies. Google Earth (http://earth.google.com) works wonders but loves to crash on older computers. Try the University of Texas at Austin’s renowned Perry-Castañeda Library Virtual Map Room (http://www.lib.utexas.edu/maps/) for a wide array of PDF maps from around the globe.
Timer, Stopwatch, Countdown. Using a simple freeware program like TimeLeft (http://www.timeleft.info), students will see exactly how long they’ve been working on a project, how much time is left, or how many days until the ice cream social after your final exam.
