Today I worked with Mrs. Wiggins 5th grade class at Altara ES. Using the Chromebooks we made Haiku Deck presentations about the Great Northwestern Tree Octopus. You can find more information about this endangered species here http://zapatopi.net/treeoctopus/. Haiku Deck is a simple presentation tool, similar to Powerpoint, that can be accessed from nearly any device as it is web based and also has an iOS app.
The students loved this activity and have a fun April Fools presentation they can share with their families when they go home!
Created with Haiku Deck, the free presentation app
An app I recently became aware of and started using is SlideShark. This is a fantastic app if you are looking for a way to present from your iPad using a PowerPoint. This powerful app has lots of features including presenter view with notes, live slide annotation, broadcast and sharing capability, and a remote option.
Teachers at Butler Middle School just started using this app in conjunction with their iPads and AppleTV. Teachers create a free account online and upload their Powerpoint presentations, or save them in cloud storage (Google Drive, Dropbox, etc). Then, you connect to your AppleTV and iPad via Airplay, and open the app. Your presentations appear in the app ready for use! The teachers at Butler love the mobility and flexibility the app offer.
This video walks you through how to use the app and how to upload your PowerPoint Presentations. Best of all...it's free! Check it out!
I presented at the UCET 2013 conference on this very topic. Check out the page I created for my presentation more in depth information and ideas of how it can be used in your classroom!
