Podcasting isn't something I plan to use with my 3rd and 4th graders. I love listening to them, but I am not a "talk to myself" while it's recording type of person. Not my favorite form of technology :)
I created my "where is it" on Tall Tale characters for grades 3 and 4.
A Summer Road Trip (Google Earth Tour)
From Birth to Missoula
I was born in Salmon, Idaho. My family moved away for a bit and then returned when I was a little over 3. I lived there until I moved away for college. I made a huge loop and ended up really close to home. We visit often because our families are still there.
