My teacher uses a Noise Meter similar to this one. The Noise Meter is a cool way to remind students the correct noise level that they should be using! You just use the paper clip and move it to the appropriate noise level the students should be using.
Students created dream jars from Roald Dahl's story "The BFG." This teacher has created a bookshelf bulletin board display, along with a large drawing of the BFG, to showcase her students' dream jar projects.
