Give students one paper plate.
Let them stamp sea creatures on the inside of the plate.
Give students another plate. Have them cut out the center. Following the center ridge. Sometimes, depending on my students ability, I make a little hole for them to start.
The have them color the outside bumps. Then cut a piece of blue saran wrap and tape on the inside. I do this myself :)
The we staple around the edges. These I only did the top, bottom, and sides. I usually add Easter Grass to look like sea weed. Then I staple a little more so the grass doesn't fall out.
