When I make Thematic Units I try to find things that are a little different. So far this unit is my largest one at 47 pages. It has all the basics of my preschool & kindergarten units.
This one I tied in a bit of Australia stuff (since the Great Barrier Reef is by Australia). We did some aboriginal art, learning about coral with a science experiment, and just had fun. Check it out.
My kids really enjoyed this one. Now they want to go to Australia too. Maybe we can all convince their father. :)
