I really had a whole lot of fun with Kidspiration, and I am sure that you can too! Kidspiration is not a completely free site, however you can start with a one month free trial. I feel that this is a great program for the classroom. This program allows your students to be creative while creating their own graphic organizers. This is a wonderful learning tool for the classroom. I would also like to mention that the teacher can also create a graphic organizer with the class, with smart boards and many interactive tolls, learning with computers is endless. You can view my own graphic organizer that I created while using Kidspiration below!
