Teaching ladder LinkedIn Crossclimb #793: students solve 5 clues before touching order. Answers: LEAD, LEND, LAND, LANE, LONE. Only then drag rungs until each neighbor differs by exactly one letter.
Middle phase answers: "Heavy metal that alchemists tried to turn into gold" = LEAD; "Give temporarily, as a tool or book, but expect to get back" = LEND; "Secure, as a job interview" = LAND; "Part of a bowling alley or swimming pool" = LANE; "___ wolf (an independent, self-reliant individual)" = LONE.
Ordering phase: the valid middle chain is LEAD → LEND → LAND → LANE → LONE. This permutation is the only valid one-letter chain for these answers.
Rule demo: DEAD and LEAD differ in exactly one slot — D→L at the first letter (DEAD → LEAD).
Rule demo: LEAD and LEND differ in exactly one slot — A→N at the third letter (LEAD → LEND).
Rule demo: LEND and LAND differ in exactly one slot — E→A at the second letter (LEND → LAND).
Rule demo: LAND and LANE differ in exactly one slot — D→E at the fourth letter (LAND → LANE).
Rule demo: LANE and LONE differ in exactly one slot — A→O at the second letter (LANE → LONE).
Rule demo: LONE and ZONE differ in exactly one slot — L→Z at the first letter (LONE → ZONE).
Lesson complete: DEAD → LEAD → LEND → LAND → LANE → LONE → ZONE. Remember — middles first, order second, combo last.
