Agenda
- Number talk: Graph Talks — a curve and its mirror image: name the mirror
- Random groups — the function machine in reverse: the output was 7; what went in, and can you always tell?
- Consolidate: The Inverse of a Function — undoing, and when the undo is a function at all
- Launch our first task: The Transformation Gallery — how it is assessed lives in How Marks Work
Things to do before our next class
- Read The Transformation Gallery and choose a parent function.
- Read Showing Your Thinking and Writing About Math — the gallery is a communication task as much as a graphing one.
