What books would have been used to teach school aged kids BASIC in a classroom setting back when BASIC was in common use? 8-Bit computers commonly came with tutorials to learn BASIC, like A Touch of AppleSoft BASIC or An Introduction to BASIC. From the late 70's through the early 90's many schools taught BASIC and I would like to harness all their hard work instead of reinventing the wheel. David Brin wrote extensively about why BASIC programming is still useful in Why Johnny Can't Code.
The "scripting" languages that serve as entry-level tools for today's aspiring programmers – like Perl and Python – don't make this experience accessible to students in the same way. BASIC was close enough to the algorithm that you could actually follow the reasoning of the machine as it made choices and followed logical pathways. Repeating this point for emphasis: You could even do it all yourself, following along on paper, for a few iterations, verifying that the dot on the screen was moving by the sheer power of mathematics, alone. Wow!
Clarification: I'm interested in US schools which general used the C64 or the Apple II. Second Clarification: I've expanded the question to school aged since elementary school is aiming very low.
