This something I had no idea it was possible to do with a powerpoint presentation, and believe it or not as I talked to my colleagues neither did they. Well, when you´re presenting a ppt after pressing the F5 key, on the bottom-left-hand corner , as you pass your mouse you can see three symbols, an arrow to return to the previous slide, and pen and an arrow to move to the following slide. Well, as you can see (marked by the red arrow on the picture above) click on the pen icon select highlighter pen and your mouse functions as one, marking anything you want to call attention to.
2- AN ONLINE STOPWATCH
I like setting time limits for some activities during my classes and I had to keep an eye on the clock all the time. With the online stopwatch, you set how many minutes you want your students to work for, click on start and the clock will ring when time is over. My favourite is the countdown clock. FANTASTIC. http://online-stopwatch.com
Thanks Joe Dale for the hints. I watched his conference from his blog last week and have learned a lot. http://joedale.typepad.com/
