At the beginning of the year I made Quiet Critters to use in the classroom. The students love them! I only bring them out sparingly, and only during those times when students need to be working quietly by themselves. Quiet Critters live in a soundproof jar and only come out when it's quiet. Loud noises hurt their ears, but whispering is ok. They love to sit on students' desks to watch and learn from the students. They don't mind being patted but they get scared if anyone picks them up or tries to play with them. When I take them out of the jar I place them on the top left hand side of the desk. If the student is too loud or starts to play with them, the Quiet Critter gets moved to the other side of their desk. If they continue to be loud they go back into their jar.
