The problem is that their interactives only work in a web browser on a computer. They are, however, slowly creating free iOS apps of their most popular online interactives.
I've been looking for a free timeline app for a long time so I was very excited to recently learn about the RWT Timeline app. With the app, students can create timelines by date, time or event. Multiple user accounts can be created so that students sharing iPads have their own space to save drafts if they don't finish in one class period. The final product can be saved to the camera roll or emailed.
Trading Cards- http://goo.gl/IhIuT6
I shared the awesome Trading Cards app on this blog in the spring. If you haven't tried it, be sure to check out the blog post to learn more.
VENN Diagram- http://goo.gl/ZG2s0O
I mentioned the VENN Diagram app in the blog post about the Mind Mapping app category. Students can create VENN diagrams with up to 3 circles. Just like the Timeline app, drafts can be saved and final products can be printed or emailed.
Stay tuned for more awesome free apps from ReadWriteThink.org!
