My students last semester were really bored with Unit 4.
We are finisheing up Unit 5 with my current semester class and it has a much better experience.
I am ready to start Unit 6, What lessons (if any) should I teach from Lesson 4 before starting 6. Some of my students had a class with me last year and others have no CS experience.
Thanks.
Mrs K.,
A lot of Unit 4 is important to get students in the mindset of user directed design instead of making things for themselves. With that said, there are plenty of ways to teach into the design cycle and empathy within your students SO the main lessons to focus on the App Lab parts are Lessons 12 and 13. If you are running short on time, just make sure that you teach the concepts of Unit 4 (empathy, user experience and then the paper prototyping is really useful) so your students have a base.
Hope that helps!
