My 3 kindergarten friendship groups all enjoyed the story, got the message of the book/lesson, and loved the activity of making a scale. Many children know the book so it is easy to reread and stop every few pages to discuss some key points. What is the problem? What kind of attitude (or how was rainbow fish acting) towards the other fish at the beginning? What advise did the wise owl give rainbow fish? How did he feel when he gave away his first scale? (Surprised he was not sad. Sharing makes both the giver and receiver feel happy.) After he gave away all his scales how did he feel? (Better about self, pleased he had so many friends). The shining scales made rainbow fish special. We all have something special about us we can share with others. For example, I love growing flowers so I share some of my plants with my neighbors. If you are good at singing, you could teach a friend a song...or a gymnastics trick, or how to play a game.
Activity: I drew an outline of the rainbow fish on bulletin board paper. I precut scales out of construction paper. I had some large shiny spangles (Lakeshore) that were left from a previous project. I gave each member one scale to draw something that makes them special they could share with a friend. I gave them each 5 spangles to glue on their scale when they finished their drawing and then they got to glue it onto the rainbow fish.
I am displaying this in my office until spring break. It would be a cute bulletin board for the hall if the lesson was done whole group.
