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).
During the Problem Solving Investigation, students are in their teams and are delegating/agreeing on what their next steps and strategies will be during a problem solving investigation. Once they are ready to begin they show the teacher a silent signal, in this case a thumbs-up. They are then dissmissed to begin their investigation using manipulatives and materials they have are given/may select from. During this time each student is given a randomized role based on their drawn number for the session. Then students select strategies to solving the problem and collaborate using the strategies they've selected from our marh strategies card. Once they agree they provide feedback or ask questions in ways to proceed forth/close out the investigation task. The students identify their next steps and are in control of their own learning. I implement this strategy to catalyze stronger teamwork skills and lifelong collaborative abilities.This strategy is developing skill sets students will need in the upper grade levels as well as in college. Basic interpersonal communication and academic language profficiencies can only flourish when ample opportunities are created in the classroom.
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.
