The Teachaholic: whiteboards! This is a cheap and quick way to make them yourself. Just buy a pack of plastic sleeves and insert card stock (paper makes it too flimsy when they display their answer). Voila! I use a ring clip to store them. EASY! You can even print lines or graph paper on the card stock if you find it useful.
classroom management idea! every time the students move from one station to another with out talking or diddle dallying their group gets a sparkler ball, once they get six they get some type of reward...like a new eraser or pencil or something not food or candy...maybe 3 minutes of play time
