The standards should always come first and not the curriculum. This year's co-teaching approach places a focus on the standards and to clearly identify exactly what students should be able to do at the completion of Math I. So our approach was to focus on the following(blue are complete thus far):
Teachers collaborate and discuss student learning outcomes throughout the week and change the material to meet the specific learning needs of the students. We focus on what we want the students to be able to do and what material, exercise, or method of instruction is best to move their learning forward. Formative assessment is active and concurrent each class period.
