My colleagues and I use a variety of hand signals in our classroom to avoid unnecessary disruptions and maintain focus and time on task. Three common hand signals: a signal to use bathroom; a signal for needing scrap paper; and a signal for asking a presenter to speak louder. We introduce all of the hand signals to students at the beginning of the year in a community-wide Town Hall Meeting.
During small group, I am able to give individualized feedback to my students. I want small group to be a safe place where my students can share, ask questions, and be able to learn content and skills authentically. This also gives me the opportunity to clarify misconceptions, to reinforce key learnings by giving my students one-on-one attention and support.
Anytime I can bring a student up for a demonstration it usually captures the other students' attention much more than I do. Having a physical connection can help with internalizing the mathematics.
Communicating and collaborating with both colleagues and students' families is crucial in a blended environment. This is especially true if a teacher is doing something that looks very different from other teachers at his school. Check out how Aaron communicates and collaborates with both his colleagues at school and his students' families and how his methods of communication and collaboration have evolved over time.
