If your students are anything like mine, they REALLY struggle with the “how would you write this code segment without the use of your selected list” written response.
My students usually have a list with a filter or randomizer. I made code.org examples of both of these to better demonstrate the concept. I will go into the “see code” portion and show my students the differences between the list and no list implementation. Feel free to use, remix, etc.
