Dip a child's foot in glue, then print onto paper. After a quick cleanup, the child can sprinkle sand on the glue. Allow to dry. Cut out a surfboard shape from a large piece of cardboard. Cover with bright paper or paint.
Children can pretend to surf the waves.
For my Hawaii unit, my class made leis. Give the children colorful cut squares of tissue paper. Use a hole puncher to punch a hole in the middle of each piece of tissue paper. Let the children use plastic needles and put the tissue papers around a string long enough to fit around the child's head. When the tissue papers are on the string, the children fluff them up and they have their very own colorful Hawaiian lei.
