One of my all time favourite book is, The Rainbow Fish, by Marcus Pfister. I remember listening to this book being read to me by my school's librarian when I was a little girl! So, I obviously had to share it with my class in the beginning of the school year. I also took this opportunity to dress-up as the Rainbow Fish!
For art, we created a school of fish. We took bubble wrap and painted on fish scales.
We also had a sensory station and explored the deep blue sea for exotic things! "I feel something prickly..."
At the end of the school day, I shared my scales with each student, just like in the book! They loved it!
