I have had a projector for a year and this year I have an ELMO. The projector is wonderful.
Our school has a subscription to
www.brainpopjr.com This has wonderful little video clips. I did have brainpopjr in my class only last year. You can have a week free trial but that week goes too fast. The site does have several free movies that can be accessed without the subscription.
Remember the Elmo is a document camera. I have only had an ELMO three weeks and it has transformed my classroom. When I use the Elmo the students can all see whatever I am doing. It eliminated whining. I even used it for story time. I use it daily in math and anything I want my students to see up close. My students love it!
I use my projector to show the students sites I want them to access in the computer lab. it is a wonderful tool. Just play with it and don't limit yourself.
