I adapted this strategy from my super awesome teacher buddy, Miss Clee! The only supplies needed are some colored construction paper! This is a great way to gauge student’s progress during independent work. Students use cards to indicate whether they are good to go (green), struggling a bit (yellow) or stuck (red).
While doing a worksheet, for example, each student has a set of cards placed on their desk. They change the cards accordingly as they work through problems.
This allows me to intervene early for students on yellow, and reteach on the spot for students on red. Additionally, if I see a whole lot of red cards at the start of the independent practice, then I can reteach to the whole class.
