In the classroom I use more websites than aps. I do have use of an ipad and will use that as a supplemental tool. For example if we are studying Jamestown, I will go on line and show them pictures of it or do an activity about it.
You tube is a nice feature at school also because you can look up educational movies and help the students understand complex concepts.
