"Dotstorming takes the process of dot voting online to allow groups of people to collaborate on a topic." A real-time group brainstorming and decision making app. Free teacher account; student accounts are not necessary.
This is a fabulous, fun typing game where users must pop bubbles by typing the letters. Steady typing scores more points and earn power-ups for typing well. You can make a free account to save your progress or just play.
I know some of us in the high school are using the book. The video and games are interesting and the kids seem to enjoy the supplemental information. (I thank Judy for originally sending me this link!)
