There are many ways to adapt and tweak this lesson. I am still in search of another book that may fit more appropriately with this lesson. Please let me know if you can think of any. Enjoy!
Link to the lesson plan:
This was taken after two classes--we later added 4 more!
We displayed this in the hallway, basically explaining the purpose of the lesson, along with the objectives.
This book works especially well if you have already read "Rainbow Fish" with the students.
