About this worksheet
A line plot shows how often each measurement happens: every object gets one X above its length. To measure to the nearest fourth of an inch, line the object up with 0 and read the last mark it reaches. The long marks are whole inches, the middle marks are halves and the short marks are fourths, so a crayon that ends 3 short marks after the 2 is 2 3/4 inches long.
Each version has eight objects drawn at actual size above a 6-inch ruler marked in halves and fourths. Print at 100% (Actual size) so the ruler matches a real ruler. Every length lands exactly on a fourth-inch mark, one length appears three times, and the line plot runs from the whole inch below the shortest object to the whole inch above the longest. The answer key fills in the table, the Xs, the most common length and the difference between the longest and shortest objects.
