In English, I love working with small groups and doing centers. In math, I find it easiest if I teach one skill but allow the class to practice it in a number of different ways, each tailored to what they need academically. In science, I love previewing a skill and then doing a number of experiments and activities to help make a concept more concrete. In history, it's a lot of whole group instruction. I do very little tests, and only spelling quizzes. I assess my students through worksheets, and other methods of formal and informal means.
