• 0-based list indexing
• For-item-in-list iteration syntax
• Index-based vs. item-based iteration over the same list
• The relationship between list length and valid index range
• Reading an IndexError traceback to locate the faulty index value
• Accumulator-variable loop pattern for sum, count, or max
• Data loss and mutation consequences of sort/filter operations on a list
• List cleaning, iteration, and accumulation applied to an unfamiliar composite data structure
• Irrecoverable information loss caused by filtering decisions made without foresight of future use
• Strings as sequences of characters, compared to lists
• The causal link between an error message’s content and the code fix it implies

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
