What are your favorite formative assessment tools that you used or would like to use in the future? I heard about the bull's eye strategy in which the students place on a stickers on a concentric circular level based on their level of comfort for a certain topic. For instance, before teaching a lesson on the ecosystem, if students feel great about their understanding of ecosystems and populations, they can put their sticker on the bull's eye ("in the zone"). If they feel comfortable, they can place their sticker on the concentric circle close to the bull's eye (e.g. "comfort zone"). If they were completely uncomfortable, they can place their stickers in the most outer circle (e.g. "twilight zone").After a couple of lessons, the students can come back and placed stickers of a different color to indicate their level of growth on the bull's eye.
