I created a project in Unit 4, which my students did after Lesson 7. They did this INSTEAD of Lesson 8, because there was no other place I knew to do it. It’s a personality profile app - like a Buzzfeed quiz. Here is my exemplar, called “What Squash Are You?” App Lab - Code.org
And here are the instructions and rubric: Personality Profile Project - Google Docs
Some students finished in less than a week, but it took about two weeks for most of them to finish.
