The Response To Intervention (RtI) process begins with high-quality instruction and universal screening of all children in the general education classroom. Formative assessment is such an essential part of the learning process that involves both the teacher and student. Formative assessment helps teachers take a snapshot of student learning—at any time during a lesson or unit of study, in any curriculum area. Students' responses give teachers a clear picture of what students know and what they need help with, what material to reteach or extend, and how to pace and differentiate instruction. Join me to learn a wide variety of formative assessment practices that can be used to assess student understanding during a lesson cycle. You will leave with a toolbox full of formative assessment ideas!
