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.

Class Dojo for Behavior Management

ClassDojo is a free behavior tracking system. I use it everyday to give students feedback on how they're meeting academic and behavioral expectations. As students are given postiive points or "needs work" points, a sound beeps and the entire class hears and sees that a student is being given feedback. Just as with behavior narration, students become more aware about their personal behaviors, following the expectations as they see them reiterated through behavior points. Their scores carry through with them to each class, culminating in a report at the end of the day that goes home to the students' parents. This allows parents to stay in the loop with how students are working and behaving at school. 

Collaborative Student Groups
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
Rotation Expectations

Before my students begin our system of rotations at the beginning of the year, I take time to make it very clear where they will go, what they will do, and what materials they will need. I also make sure to do frequent checks for understanding. Dedicating extra time to review Rotation Expectations at the beginning of the year helps to ensure that rotations will run smoothly throughout the year. Class tutors are also selected for each rotation. They walk around to support their peers who need help and even help to manage class behavior. Class tutors are given an iPad with access to our ClassDojo site, where they award "positive points" to students following expectations and "needs improvement points" to those who are not following expectations. Through explaining my expectations and leveraging the class tutor to reinforce these expectations, I ensure that my students are giving their best efforts during our rotations.
