## Reflection: Writing Across the Disciplines Absolute Value Functions: Transformations Day 1 - Section 4: Reflections, Stretches, and Shrinks of Absolute Value Functions

Engaging students in a lesson is fundamental in a Common Core classroom.  Gone are the days of mindlessly copying down notes taken from a text book.  I tell my students that my lessons are an experience.  With this in mind, I very rarely pre-write a definition or description of a mathematical concept into my PowerPoints.  This is something that is developed in class.  Often, we will talk about the concept, highlight key terminology, and then each student will write their own description.  This is crucial to their understanding.  Here is an example from today’s Notes on transformations.  One drawback comes from students whose summaries are not up to par due to misunderstanding or lack of effort.  I use several strategies to combat this.  I walk around and do a visual check during class where I can encourage and correct their efforts.  I often have students share their summaries with their partner which adds a layer of accountability and error detection.  Finally, I regularly check notes for points which ensures that they are putting forth a decent effort.
