  1. 2 1/2 inches · Halfway between 2 and 3 inches is 2 1/2 inches, the half-inch mark.
  2. 3/4 · Three of the four equal quarters are shaded, so the length is 3/4 inch.
  3. True · Every X is one measurement. Two X's above the same mark mean two objects had that same length.
  4. 2 1/2 inches · 2 1/2 inches has the tallest stack of X's, two in a row, so it is the most common length.
  5. 2 · Two pencils measured 5 1/2 inches, so that mark gets two stacked X's.
  6. 4 1/4 inches · Each quarter-mark adds 1/4 inch, so one quarter past 4 inches is 4 1/4 inches.
  7. 2 · Three pencils measured 2 1/2 inches and one measured 2 inches, so that is 2 more.
  8. He rounded to the wrong nearest mark · 2 3/4 inches is closest to the 2 3/4 mark, not the 3-inch mark, so Jake's X belongs one mark to the left.
