Great app for students demonstrating what they know about a topic.
I'm a huge fan of Educreations. I think the app has great features and can be used in any content area. I haven't used it in any other way outside of a centers type activity, but I think it would work great in Math for students to describe how to solve a particular math problem and students can use the app to teach each other. It's highly engaging and different than the basic paper/pencil way of doing things.
How I Use It
I used this product as a centers station while my students were learning about compound sentences. When students came to the station, they had to create a short demo on how to write a compound sentence. This included their voice narrating as they wrote the compound sentence. The app worked well, and my students were highly engaged. It was also easy for me to check to see if they understood the compound sentence.
