Line up the left ends and see which reaches furthest. For clues: if A is longer than B and B is longer than C, then A is longer than C too.
longerreaches further
shorterdoesn't reach as far
longestthe longest of all
shortestthe shortest of all
Watch for: Comparing things whose left ends don't line up. Picking the name said last in the clues instead of thinking it through. Writing the order from longest to shortest when it asks the other way.
At home: Lay three spoons, shoes or crayons side by side with one end lined up. Ask which is shortest and which is longest.
