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.
Even with the best set of directions students still needed some guidance or individual assistance. My school currently uses a full inclusion model (Special Education students are included in the general education classes) and SPED students often need additional support. I want all my students to learn to be independent and take ownership of their learning but I also do not want them to "suffer in silence" if they need help or are incapable of access the material. Having a co-teacher adds an extra set of hands and eyes to the classroom and gives my the flexibility to even create multiple classrooms within the class.
My students respond well to kinesthetics. Popping up for an answer choice or when they are ready to move on to the next topic is a way to keep the students engaged and also check for understanding. Turn and talk - students turn to talk to their neighbor about a question/problem/scenario that was posed. One of the partners then reports out by either being chosen from the equity sticks or by volunteering by putting their thumb up. I use Shoulder Partner strategy to give students the opportunity to talk, share and explain content to each other. This strategy is good to increase the accountable talk in classrooms and to practice speaking and listening skills.
During Personalized Small Group Instruction, I work closely with a small group of students while other students are engaging in activities independently at different stations. Based on my learning objective, I group my students differently for Small Group Instruction every day. Sometimes students are grouped homogeneously, according to specific needs, and sometimes they are grouped heterogeneously. This strategy, which is enabled by my station rotation blended model, allows me to spend individual time with each student on a regular basis.
