For grown-ups

These are the ten practice questions from the Unit 6 casebook, in order: warm-up (Q1–3), explorer (Q4–8), challenge (Q9–10). The working is shown after every answer — especially on the two balance true/false cases and the far-term prediction, where the two big misconceptions live: reading "=" as "the answer comes next", and continuing a pattern instead of naming its rule. Full worked answers and extension prompts are in the book's Answer Key.
