Blendspace! What a beautiful layout to use for your presentations. I used Blendspace last year for a lesson and LOVED IT, but only for presenting.
Now there are all these interactive features that make your presentation into an engaging LESSON and possibly a flipped lesson?
Check out this Blendspace for a great example.
The most amazing function that they include now is a lesson library! You can search by TEKS and voila! You have pieces of your next lesson. (Don’t recreate the wheel!)
Another great feature is that while you are presenting students can discuss and talk with you and each other!!
It’s free and it’s a great resource, GO TRY IT!!!
