Which ruler has a red circle around the \(\frac{1}{4}\) inch line between the 1 inch and 2 inch lines?
Sorry, that is not right. The ruler shows the \(\frac{1}{2}\) inch line between the 1 inch and 2 inch lines.
Sorry, that is not right. This ruler shows the 1 inch line. Try again!
That is right! This ruler shows the line that is halfway between the 1 inch line and the \(\frac{1}{2}\) inch line.
Which ruler has a red circle around the \(\frac{3}{4}\) inch line between the 6 inch and 7 inch lines?
Correct! This ruler shows the line that is halfway between the \(\frac{1}{2}\) inch line and the 7 inch line.
Sorry, that is not correct. The ruler shows the line that is halfway between the 6 inch and 7 inch lines.
Sorry, that is not correct. This ruler shows the \(\frac{3}{4}\) inch line between 10 and 11 inches, not between 6 and 7 inches. Try again!
Use the ruler to measure the length of the line to the nearest quarter of an inch.
A line that is about 4 and a half inches long.
- about 3 \(\frac{1}{2}\) inches
- about 3 inches
- about 4 inches
- about 4 \(\frac{1}{2}\) inches
Sorry, that is not right. The end of the line is not close to the \(\frac{1}{2}\) inch line between the 2 inch and 3 inch lines on the ruler. Try again!
Sorry, that is not right. The end of the line is between the \(\frac{1}{4}\) inch and \(\frac{1}{2}\) inch lines on the ruler. It is not close to the 3 inch line.
Sorry, that is not right. The end of the line is between the \(\frac{1}{4}\) inch and \(\frac{1}{2}\) inch lines on the ruler. It is not close to the 4 inch line.
That is right! The end of the line is close to the \(\frac{1}{2}\) inch line between the 4 inch and 5 inch lines on the ruler.
Use the ruler to measure the length of the line to the nearest quarter of an inch.
A line that measures about 8 \(\frac{1}{4}\) inches
- about 8 \(\frac{3}{4}\) inches
- about 9 inches
- about 8 inches
- about 8 \(\frac{1}{4}\) inches
Sorry, that is not correct. The end of the line is not close to the \(\frac{3}{4}\) inch line between 8 and 9 on the ruler. Try again!
Sorry, that is not correct. The end of the line is not close to 9 on the ruler. Try again!
Sorry, that is not correct. The end of the line is between 8 and the \(\frac{1}{4}\) inch line. It is not closer to the 8.
Correct! The end of the line is close to the \(\frac{1}{4}\) inch line between 8 and 9 on the ruler.
Use the ruler to measure the length of the scoreboard to the nearest half inch.
A scoreboard that measures about 20 \(20{3}{4}\) inches
- about 20 inches
- about 20 \(\frac{3}{4}\) inches
- about 20 \(\frac{1}{2}\) inches
- about 21 inches
Sorry, that is not right. The right end of the scoreboard is not close to 20 on the ruler. Try again!
That is right! The right end of the scoreboard is close to the \(\frac{3}{4}\) inch line between 20 and 21 on the ruler.
Sorry, that is not right. The right end of the scoreboard is between the \(\frac{3}{4}\) inch line and 21 on the ruler. It is not closer to 20 \(\frac{1}{2}\) .
Sorry, that is not right. The right end of the scoreboard is between the \(\frac{3}{4}\) inch line and 21 on the ruler. It is not closer to 21.
Measure the length of each line below to the nearest quarter of an inch. What is the length of the longer line?
Two rulers. The first ruler is measuring a line that is about 10 inches. The second ruler is measuring a line slightly shorter than 9 inches.
- about 10 inches
- about 9 \(\frac{1}{2}\) inches
- about 9 inches
- about 8 inches
Correct! The end of the longer line is close to 10 on the ruler.
Sorry, that is not correct. The end of the longer line is between the \(\frac{3}{4}\) inch line and 10. It is not close to 9 \(\frac{1}{2}\) .
Sorry, that is not correct. The end of the shorter line ends near 9. Look at the longer line!
Sorry, that is not correct. Neither of the lines ends near 8 on the ruler.
Measure the length of each water bottle below to the nearest quarter of an inch. What is the length of the longer water bottle
Two flags being measured. The first flag measures about 6 \(\frac{1}{2}\). The second flag measures slightly past way past 5 \(\frac{3}{4}\) inches.
- about 6 inches
- about 6 \(\frac{1}{2}\) inches
- about 5 \(\frac{3}{4}\) inches
- about 7 inches
Sorry, that is not right. The shorter bottle ends near 6 on the ruler.
That is right! The end of the longer bottle is close to the \(\frac{1}{2}\) inch line between 6 and 7.
Sorry, that is not right. The end of the shorter bottle ends near the \(\frac{3}{4}\) inch line between 5 and 6. Look at the longer bottle.
Sorry, that is not right. The end of the longer bottle is between the \(\frac{1}{2}\) inch line and 7. It is not closer to 7.
Measure the length of each basketball shoe to the nearest quarter of an inch. What is the length of the shoe with the greater length?
Two shoes being measured. The first poster measures about 12 \(\frac{1}{4}\). The second poster measures almost 12 \(\frac{3}{4}\) inches.
- about 12 inches

- about 12 \(\frac{1}{4}\) inches
- about 12 \(\frac{3}{4}\) inches
Sorry, that is not correct. Neither of the shoes ends closer to 12 on the ruler.
Sorry, that is not correct. Neither of the shoes ends closer to 13 on the ruler.
Sorry, that is not correct. The end of the shorter shoe ends near the \(\frac{1}{4}\) inch line between 12 and 13 on the ruler. Look at the longer shoe!
Correct! The end of the longer shoe is close to the \(\frac{3}{4}\) inch line between 12 and 13 on the ruler.
Read the word problem below. Measure the line, and then choose the correct answer.
Zoe needs to stand about 19 \(\frac{1}{4}\) inches away from the net to make a special shot. This line below shows how far Zoe was from the net when she made a basket. Was Zoe the correct distance from the net to make her shot?
