FirstClass

For those with access to FirstClass, there's a dead simple PowerPoint-like option. Go "File/New Presentation", and start creating. It's kind of like HyperStudio too. I know we use it at our school and so students have access to it at home and can collaborate with classmates. Our school does not have access to PowerPoint, so this is a great alternative! They're all using the same software and can use it at school or home. Mom and dad are able to see what their child is doing and how they're working with other students. I really like it.
