Teaching ladder Crossclimb Level 8: students solve 5 clues before touching order. Answers: MILD, MOLD, COLD, BOLD, GOLD. Only then drag rungs until each neighbor differs by exactly one letter.
Middle phase answers: "Not spicy" = MILD; "Fungus growth" = MOLD; "Freezing temperature" = COLD; "Brave and daring" = BOLD; "Precious metal" = GOLD.
Ordering phase: the valid middle chain is MILD → MOLD → COLD → BOLD → GOLD. Note: reverse order also steps one letter at a time, but only this orientation matches the stored top and bottom slots.
Rule demo: MIND and MILD differ in exactly one slot — N→L at the third letter (MIND → MILD).
Rule demo: MILD and MOLD differ in exactly one slot — I→O at the second letter (MILD → MOLD).
Rule demo: MOLD and COLD differ in exactly one slot — M→C at the first letter (MOLD → COLD).
Rule demo: COLD and BOLD differ in exactly one slot — C→B at the first letter (COLD → BOLD).
Rule demo: BOLD and GOLD differ in exactly one slot — B→G at the first letter (BOLD → GOLD).
Rule demo: GOLD and HOLD differ in exactly one slot — G→H at the first letter (GOLD → HOLD).
Lesson complete: MIND → MILD → MOLD → COLD → BOLD → GOLD → HOLD. Remember — middles first, order second, combo last.
