Have the children make small scales to attach to Rainbow Fish with push pins. These can be decorated with iridescent nail polish, fluorescent poster paints, glitter, foil, or small beads. Write each child's name on one of the other paper fish. Whenever a child finishes reading a book, move one of the Rainbow Fish's shiny scales to that child's colored fish. Ask children to locate the oceans and seas on a globe or world map.
Children can make a large ocean mural.
Begin by painting a mural of the ocean as a background for their sea life. Individual fish, starfish, and octopuses can be painted on construction paper, then cut out and glued to the mural. Have children make Rainbow Fish friendship chains. Students write their names on strips of colored paper, then exchange slips with their classmates. Once they have a nice collection of slips, they paste the strips into links to form a chain, which they can wear around their necks.
