In the never ending commitment to enhance the presentation of content, I give you SKITCH! This freeware, in beta version, is truly dynamic and has changed the way I review homework or introduce new material. Skitch allows you to snap, draw and share. I use this tool in conjunction with my wireless Wacom tablet. I am able to quickly access the internet, open Skitch, click on snap which displays cross-hairs that enable me to snap a shot of whatever I would like to highlight. Then I can annotate or draw on the whatever I have snapped. Avery simple tool with and endless amount uses. Go check it out. Download it. Have fun while getting your students attention.
