Look at where each one starts and where it ends: the one that reaches further is longer. For towers, the one reaching highest is tallest.
longerreaches further from end to end
shorterdoesn't reach as far
tallerreaches higher from the bottom
comparelook at two things to see how they differ
Watch for: Picking the thicker one, like a fat crayon, instead of the longer one. Going by real life (pencils are longer than crayons) instead of the picture. Circling the shorter one when the row asks for the longer one.
At home: Hold two spoons, shoes or crayons side by side with their ends lined up. Ask which is longer, then which is shorter.
