Best two ideas for technology integration

The first idea that I enjoyed the while watching my peers' presentations was on math. The students were able to come up and use a promethian (sp?) board tot calculate math problems. I thought that was a really great idea. The second idea was to have the students use kidsperation to sort and classify objects. The objects were all science related and it fit very well with the technology because it allowed the students to classify things they wouldn't really be able to bring to class and sort.
