Teachers need feedback from their students constantly to make good decisions. One way I check what my students brains are doing is through Post it Power. This strategy involves students writing an answer to either a reflective question or math problem that will illuminate their understanding. Using this information, I get a powerful, visual snapshot of the class that helps me to make decisions about the following days' lesson.
1:1 interventions take place with students who are far below grade level. Though we try to keep them exposed and practicing grade level content, I need to meet with these students additionally to spiral in remediation support so they can better access the content we learn as a class.
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.
This collaborative strategy is simple but effective. Students roam the room finding new questions to answer together, and scan the code with an iPad to check their work. Then, they put all the answers together to unlock a secret code. The use of QR codes in class has greatly improved the effectiveness of student work because of their ability to stop and check their answers. Their enthusiasm for this activity is clear, and making it into a competition of sorts makes it all the more fun. I utilize the QR codes in everything from directions to links to activities. Still, my favorite use is monitoring groups during QR code breakers.
