Slideshare

Check out slideshare at http://www.slideshare.net/

SlideShare is the best way to share your presentations with the world. Let your ideas reach a broad audience. Share publicly or privately. Add audio to create a webinar.

You can search for slideshows on a specific topic. If someone already did one, why recreate the wheel, simply borrow what you need and keep going.

Eclipse Crossword/ Puzzlemaker

Crosswords are easy with Eclipse - http://www.eclipsecrossword.com/

I've used this tool to create crosswords from my vocabulary. The best feature may be that you can save them and post them online. This one is linked from my wiki page - http://wesleyantech.wikispaces.com/space/showimage/Office-Ch1-Vocab.html
My students can do this online. No more printing sheets to hand out.

I've used Puzzlemaker and that one is good too. http://puzzlemaker.discoveryeducation.com/
Puzzlemaker is better if you want to do different kinds of puzzles but you can't link them online in a wiki.

Voice Thread

Voice Thread is a cool new tool that I have begun using. You can upload pictures and make a slide show. You can add audio files. There are tools that you can annotate on the picture while you are talking about it. These files are then on the internet and you can share them with others. Other people can leave comments on specific parts of your show.
