• Binary-decimal place value conversion for 8-bit values
• ASCII character encoding of byte values
• The relationship between a bit pattern and the encoding convention applied to it
• Lossy vs. lossless compression as different information-preservation guarantees
• Data collection and encoding choices embedded in a specific real dataset
• Design tradeoffs in creating a new binary encoding scheme
• The distinction between sampling bias and encoding bias in data collection
• The multi-step ASCII decoding procedure (bits to decimal to character)

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.
