How do you differentiate in a class of 25?

When I first got into the class I would be in for my 3 weeks of field, I was overwhelmed with how to differentiate for 25 very unique students. I wanted to meet their learning needs individually but that seemed like a daunting task. I was very lucky and was placed with a teacher who is great at differentiating and meeting the needs of each individual student. At the beginning of the day Mrs. T has a student who is the "head farmer" which means they get to lead the morning work. After all the morning work is done, she goes over it with her students to make sure they understand what is being taught. She meets so many students' needs by teaching this way. One thing I loved that Mrs. T did was she allowed her students to read each day in front of the other students if they wanted to. This allowed the students to chose when they wanted to read aloud and not be forced to do something they were uncomfortable with. What a great way to DIFFERENTIATE!!!!
