Teaching ladder LinkedIn Crossclimb #888: students solve 5 clues before touching order. Answers: REAM, ROAM, FOAM, FORM, WORM. Only then drag rungs until each neighbor differs by exactly one letter.
Middle phase answers: "Package of 500 sheets of paper" = REAM; "Travel without a plan" = ROAM; "Type of cushioning or rubber" = FOAM; "Something you might fill out with your name and address" = FORM; "“The early bird catches the ___”" = WORM.
Ordering phase: the valid middle chain is REAM → ROAM → FOAM → FORM → WORM. This permutation is the only valid one-letter chain for these answers.
Rule demo: TEAM and REAM differ in exactly one slot — T→R at the first letter (TEAM → REAM).
Rule demo: REAM and ROAM differ in exactly one slot — E→O at the second letter (REAM → ROAM).
Rule demo: ROAM and FOAM differ in exactly one slot — R→F at the first letter (ROAM → FOAM).
Rule demo: FOAM and FORM differ in exactly one slot — A→R at the third letter (FOAM → FORM).
Rule demo: FORM and WORM differ in exactly one slot — F→W at the first letter (FORM → WORM).
Rule demo: WORM and WORK differ in exactly one slot — M→K at the fourth letter (WORM → WORK).
Lesson complete: TEAM → REAM → ROAM → FOAM → FORM → WORM → WORK. Remember — middles first, order second, combo last.
