This strategy is a biweekly problem solving investigation on recently learned content. Typically students will be given sample scanned answers that I have hand selected. These problems have been previously solved. Students meet on the carpet for the mystery problem reveal. We also cover what the goal of our session will be using a checklist/success rubric. They are then dismissed to investigate in teams. The students select manipulatives to discuss, develop an agreed upon idea, and critique which student(s) response they agree with/why. If a team finishes early they can work on they "Step ahead" which is harder differentiated task. Finally they use the checklist to self reflect if they were successful during the mystery problem session.
Observation charts are a type of inquiry chart that stimulate students’ curiosity. They build background information while providing teachers with a diagnostic tool. And they provide opportunities for language support from peers. During an observation chart, I use real pictures or paintings attached to white poster paper or butcher paper that contain a theme (e.g., food from a culture, ways of transportation, games a culture plays, etc.). My students walk around from observation chart to observation chart and write down either a question they're wondering about, a comment they'd like to make, or just an observation (i.e., statement of fact).
At the conclusion of our team sessions my students self-assess, give feedback/compliments to one another, and agree or share out their disagreements with one another. Our two areas of focus right now are collaboration and accountability. My students score themselves on a scale from 1-4 on these habits and then track their progress daily/weekly in order to consider their next steps or provide feedback to one another. Perhaps most importantly, the sentence stems within the rubric help my students develop a repertoire of conversational skills they will need in the 21st century and beyond.
My students engage in a strategy called Math Fact Fluency for a few minutes each class period. They use a dry erase marker to fill in a blank multiplication table inside a plastic sheet protector according to a specific rule (by 2s, by 5s, etc.). I use this strategy to help my students notice patterns within the multiplication table and to develop a deep conceptual understanding of multiplication.
