I want to share a wonderful wonderful blog with you: Kindergarten...Kindergarten. Kathryn's posts are so wonderfully laid out with detailed information about math and science topics along with downloads! For example, today she posted a unit about rocks complete with a unit to download, a wonderful ppt to introduce rocks and great pictures. Visit Kindergarten...Kindergarten and you'll return again and again. Thank you Kathryn for all the wonderful things you share.
