Fossil Prints Making fossils is great fun, and really not as "troublesome" or "messy" as you might think. Learning how fossils are formed and leaves children with a lasting impression! We keep our fossils in our garden.
Fossil Crafts, good method to impress in clay, then plaster since plaster dries too fast and does not give great details. Tried salt dough and it doesn't work for impressions, plaster would dry by the time I got it to all kids in program.

Math Workshop- this teacher explains exactly how she conducts her guided math lessons in her third grade classroom. (extremely informative post that includes a FREEBIE!) and now she also has detailed lesson plans!
