Voki is a great website that allows users to create speaking avatars. It provides a variety of different avatars that can be selected, including historical figures. You can add speech using typed text, recorded voice or your cell phone. This would be great if you had limited access to a microphone or other recording hardware. Voki also provides users with the ability to change the voice that is speaking. For teachers, it provides lesson plan ideas incorporating Voki. Voki Classroom allows teachers to set up accounts for their student without requiring an email address, which is a great feature for elementary aged students.
ToonDoo is a website that allows students to create cartoons, books, characters, or doodles about any topic. It would be a great way for students to present information they have learned or demonstrate comprehension in a non-traditional way.
