Grade 1 Measuring Test Answer Key: questions 1–5
Question 1: Longer or shorter (2 points)
- Pencil A reaches farther. The longer pencil is Pencil A.
- Pencil B stops sooner. The shorter pencil is Pencil B.
Scoring: 1 point for each correct pencil.
Question 2: Order the ribbons (3 points)
Ribbon B stops first. Ribbon C reaches the farthest. Ribbon A is in the middle.
The order is B, A, C.
Scoring: 1 point for the shortest (B), 1 point for the middle (A), 1 point for the longest (C).
Question 3: Count the cubes (2 points)
- Count the cubes: 1 to 9. The pencil is 9 cubes long.
- 9 is more than 6. The pencil in the picture is longer.
Scoring: 1 point for 9 cubes. 1 point for choosing the pencil in the picture.
Question 4: Find the mistake (3 points)
- Sam left gaps between the cubes. Gaps leave out part of the length, so his count is too small.
- Sam can lay the cubes so they touch, with the first cube at the left end.
Scoring: 2 points for naming the gaps and saying why this is wrong (1 point for naming only). 1 point for a correct fix.
Question 5: Use a third object (2 points)
The string matches Ava’s desk. Ben’s desk is shorter than the string. So Ava’s desk is longer.
Ava’s desk is longer.
Scoring: 2 points for Ava’s desk. 1 point if the answer is wrong but the work shows the string was used.
Grade 1 Measuring Test Answer Key: questions 6–8
Question 6: Longest and shortest (2 points)
- 13 is the biggest number. The plane is the longest.
- 5 is the smallest number. The bus is the shortest.
Scoring: 1 point for each correct toy.
Question 7: Count the clips (3 points)
- The crayon is 6 paper clips long.
- The spoon is 9 paper clips long.
- 9 is more than 6, so the spoon is longer.
Scoring: 1 point for each part.
Question 8: Toy trains (3 points)
- 8 is more than 5, so Noah’s train is longer.
- \(5 + 3 = 8\). Ella’s train is 8 cubes long.
- Both trains are 8 cubes long. The answer is yes.
Scoring: 1 point for each part. In part (c), give the point for a yes that matches the answer to part (b).
