Collaborative Student Groups

CSI Time

CSI Time is an inquiry based strategy where students must solve a "math mystery" that introduces a concept that we will learn. They have until the end of the week to collaboratively (with their detective partner) discover the clues and work their way to the "criminall". In just 10 minutes, students have worked themselves into a frenzy to grapple with content they may not already know what to do with. This desire to problem solve pushes students during the lesson that follows to learn the skills they need to solve the mystery.

Carpet Transitions

Carpet Transitions is a process where students walk from their desks to the carpet (or another location) for the next activity. Expectations and directions are explicitly laid out, and we evaluate how our transitions go. As we perform these transitions more and more, we emphasize our efficiency and use of our time. Through this process, we make the most of our learning time and ensure students transition safely.

Student-Led Homework Review

Student-Led Homework Review is a form of differentiation, where students with the same level of homework collaborate and review their homework assignment from the prior night. Since it would take too long to have teacher-led reviews for each group, we have students share their answers and help each other figure out the correct answers with their peers. Though I sometimes give them answer keys, I push students to discuss problems and figure out the correct solutions through their reasoning skills. This process encourages collaboration and accuracy in students' homework practice.

Routines and Procedures

I begin every Math class with a high-energy strategy called Threshold. Students line up outside the classroom door "dressed for success" in their uniforms with their shirts tucked in. After a group greeting, a Math chant (practicing our multiples), and instructions for entering, my students walk to the door, shake my hand, enter the room, and immediately begin a Math warm-up. Threshold ensures that all of my students transition from their previous class smoothly and that their minds are ready for Math instruction.
