Question 4
Tim measures a book with cubes. He leaves big gaps between the cubes. What is wrong with how Tim measures?
Correct answer: C
Units must be placed end to end with no gaps. Gaps leave parts of the book unmeasured, so Tim would count too few cubes.

Question 5
A desk is 9 hand spans long. A rug is 14 hand spans long. Both were measured with the same hand. How many hand spans longer is the rug?
Correct answer: B
Find the difference: 14 − 9 = 5. The answer 23 adds the lengths, which does not tell how much longer the rug is.
-
Question 6
Zoe measures a shoe with paper clips and gets 6 paper clips. Then she measures the same shoe with big blocks. Each block is longer than a paper clip. What will be true?
Correct answer: C
Bigger units cover more length each, so it takes fewer of them. The shoe itself does not change.

Question 7
Look at the strips.
Which strip is the shortest?
Correct answer: B
All strips start at the same place. Strip 2 ends first, so it is the shortest. Strip 3 is the longest.
-
Question 8
Ben made a snake that is 7 cubes long. Ann made a snake that is 3 cubes longer than Ben's. How long is Ann's snake?
Correct answer: A
Ann's snake is 3 cubes longer, so add: 7 + 3 = 10 cubes. The answer 4 subtracts instead.
-
Question 9
A pencil is 8 cubes long. An eraser is 3 cubes long. How much shorter is the eraser than the pencil?
Correct answer: D
Compare the lengths by subtracting: 8 − 3 = 5 cubes. The answer 11 adds the two lengths.
-
Question 10
Which word makes this sentence true?
A giraffe is ______ than a cat.
