I spent 20 years as a public school teacher and am still active in the Advanced Placement Computer Science teacher community. This is good stuff, and very well-regarded by my colleagues. Depending on the age of your kids, https://automatetheboringstuff.com/ https://automatetheboringstuff.com/ or another of Al's books are quite good to start with and free to read. For younger kids, Code.org's "Hour of Code" stuff uses Scratch, which is a nice block-based visual programming language that's still a real enough language under the hood; I had co-workers who used Scratch to have their AP CS students sorting lists of numbers and other "real" algorithmic tasks. And I'd be remiss if I didn't mention the book I wrote, which is linked in my bio.
