You are working with a middle school class that loses focus easily and over half of the students struggle with fraction concepts. Design a bridging activity linking addition and subtraction of fractions to an abstract, pencil and paper assignment. Be sure to explain the teaching sequence carefully as if leaving exact notes for a substitute teacher who has never seen or used the activities before. Include some scripting as well. I will attach the chapter notes i have taken, please review them carefully and use appropriate terminology and procedures outlined in the notes.
