It bills itself as “The Complete Middle School Study Guide” and it does have a load of content.
Everything you need to ace computer science and coding in one big fat notebook is a fat book full of color drawings that covers coding concepts and computer languages.
I used it to teach Scratch. I like how it explains the coordinate plane, because not ever student knows what the numbers in the move blocks mean.
I also learned about the scratch backpack, on area on the bottom of the scratch page that you can use to save scripts to reuse with other sprites (characters) or other projects. Students must have an individual Scratch account to use the backpack feature, fyi.
The book has a unit on universal coding commands, such as loops, conditionals, and variables, that I found confusing and not helpful.
