OUR ACTIVITY TODAY Pick a rock from the rocks you brought
in. Decide what kind of rock it is, then
decide a use for your rock. Glue your rock onto cardstock, and draw
a picture of the use, using your rock. Write what kind of rock you chose and how you are using your rock on a piece of lined paper.
When you are finished, put away your materials, leave your picture to dry, and bring your lined paper to your row on the carpet and be ready to share!
