Here's one for Chicka chicka fans. Carpet tubes are usually available from carpet retail stores for free. I like to use the 12 footers, but there are also eight foot tubes as well.
Use the tube for your coconut tree trunck and add various shades of green paper cut into leaf shapes. Brown balloons make great coconuts. Use large die-cut letters and let the kids add them to the trunk with tape or glue. It is great fun to reinact the story while listening to it on tape. Be forewarned! Once it is up in your classroom, the students won't want you to take it down anytime soon!
