How I Use It
I use the short practice lesson for my annual Hour of Code. This does not require any sign-in but it does not save work. My fifty most advanced students have individual accounts, which I created by copying their names from a spreadsheet. It took me about 15 - 20 minutes originally to set up my teacher account, create my class, then add students. It takes me about 5 - 10 minutes each year to remove some students and add new ones. This year, I just deleted my entire roster then copy and pasted new names in just a few quick minutes.
I primarily use Kodable with students who are not strong readers because of their age or their disabilities. I also use Kodables as a wonderful introduction to coding for students who will move on to text-based block coding. Both groups of students enjoy Kodables as long as they have a good sense of cause/effect, first/next, and if/then. Some students who are still on the most basic cause-and-effect level or a little above enjoy watching the Fuzzsz move, but they do not understand what is going on. Even a few of my most involved students can learn to press the Play button after their classmates move the arrows.
I enjoy using Kodable for my younger students and my pre/early readers. As I said above, it can also be a fun way to introduce mt students who know how to read to coding. I have had a few students finish Kodable then move on to block-coding with blocks of words.
