About this worksheet

Before children measure precisely, they need to compare and order lengths directly. First graders learn to decide which object is longer or shorter, arrange several objects by length, and reason about differences. This sounds simple, but children may be distracted by where an object is placed on the page or by its color. The mathematical comparison depends on endpoint alignment and equal units. This worksheet uses rows of same-size objects that all start at the same place to ask which item is longer, which is shorter, how much longer one item is, and what order fits three lengths.

Support pages use clear differences. Standard and challenge versions include closer lengths and mixed language so the child must read the comparison word carefully. Ask children to line up imaginary starting points before deciding.
