Please leave any feedback, thoughts, or resources for the lesson here. As a reminder, good feedback has the following elements: - description of your school and classroom context - details on what went well when teaching this lesson - details on what **didn’t** go well when teaching this lesson - a description of the changes you would recommend to improve the lesson (including formative assessment opportunities you added to the lesson) - details on the types of deviations you made from the lesson For more details on what good feedback looks like, check out the [feedback guide](https://docs.google.com/document/d/1Nv7072tzl3ZaOLdE7pii3i0fXzCiYdxO4mzHrmJcw6U/edit#)! ---

The lesson plan references an abstraction video. I don’t see one yet in the links. Is this going to be added later? ---

Yes we will eventually have videos in this chapter that explain how abstractions help us more simply express complex behavior (e.g. collision detection) but it hasn’t been produced yet. ---
