Measuring Lengths — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A fork is 6 inches long. A spoon is 5 inches long. The fork is longer.
6 > 5, so the fork at 6 inches is longer than the spoon at 5 inches.
2. A glue stick is 3 paper clips long. A tape roll is 7 paper clips long. The tape roll is 4 paper clips longer.
7 - 3 = 4, so the tape roll is 4 paper clips longer than the glue stick.
3. A shoe is 8 inches long. A sock is 6 inches long. The shoe is 2 inches longer.
8 - 6 = 2, so the shoe is 2 inches longer than the sock.
4. Three erasers measure 2 inches, 5 inches, and 3 inches. The shortest is 2 inches.
Comparing 2, 5, and 3, the smallest number is 2, so the shortest eraser is 2 inches.
5. A toy car is 4 cubes long. A toy truck is 9 cubes long. The toy car is 5 cubes shorter.
9 - 4 = 5, so the toy car is 5 cubes shorter than the toy truck.
6. A belt is 12 inches. A scarf is 12 inches. They are the same length.
Both the belt and scarf measure 12 inches, so they are the same length.
7. A key is 3 hands long. A remote is 5 hands long. The key is shorter.
3 < 5, so the key at 3 hands is shorter than the remote at 5 hands.
8. Three strings measure 8 cubes, 3 cubes, and 6 cubes. The longest is 8 cubes.
Comparing 8, 3, and 6, the greatest number is 8, so the longest string is 8 cubes.
9. A toothbrush is 7 inches. A comb is 9 inches. The comb is 2 inches longer.
9 - 7 = 2, so the comb is 2 inches longer than the toothbrush.
Part B: Match
Draw a line from each item on the left to the correct answer on the right.
1.
measuring with cubes
→ nonstandard unit
8 inches
measuring with inches
→ standard unit
standard unit
longer than 5 inches: 3 in or 8 in?
→ 8 inches
2 inches

→ 2 inches
nonstandard unit
Cubes are a nonstandard unit. Inches are a standard unit. 8 inches is longer than 5 inches. Among 6, 2, and 5 inches, 2 inches is the shortest.
