I'm trying out a new multimedia presentation tool called "Tes Teach with Blendspace." It's new and a little buggy, but I see great potential in it! You can upload pictures or files, add videos or links, and then organize all of these components into a single presentation, lesson, or unit. You can even add teaching notes and student quizzes for your students to take individually. Check out the Squishy Circuit lesson plan I made by clicking here.
