This website is great, because it gives so many great ideas for using recycled materials in the classroom. I found this one and thought of Katie because it is a jellyfish and it is made out of lid and bubble wrap. This would be a great activity to make during an under the sea lesson, animal activity or even a exciting decoration for your classroom.
Rainbow Fish and positive classroom behavior management... each child has their own Rainbow Fish. Give stickers out for positive reinforcement and have them "decorate"their Rainbow fish. Once they reach a predetermined number of "scales," they can swap their Rainbow Fish for a prize!
