As I read through some of the posts I totally agree that some of the Code.org Unit 1 Chapter 1 questions require teachers to pull additional resources to explain binary, octal, decimal, and hexidecimal conversions. Also, I thought 10 questions was not enough, so I created an additional 20 point test using a variety of resources. My students took the online 10 point test and my 20 point test. I wanted to share with everyone but I received a message “new users can’t upload a document” Oh well, I thought it was a great test, yielded typical bell curve results. Anyone knows how a new user can upload a document, let me know.
