Measuring Length — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A kitchen counter is about 3 feet high.
A kitchen counter comes up to about waist height on a grown-up. That is about 3 feet, which is the right unit for things bigger than a ruler.
2. A skateboard is 30 inches long. That is 2 feet and 6 inches.
Every 12 inches makes one foot. From 30 inches you can take out two groups of 12, which equals 24 inches (2 feet), leaving 6 inches extra.
3. A stamp is about 2 centimeters wide.
A postage stamp is tiny, about the size of a fingernail. Centimeters are the right unit because inches, feet, or yards would all be too big.
4. Mia has a ribbon 15 cm long and another 20 cm long. Together they measure 35 cm.
To find the combined length, add the two pieces together: 15 cm + 20 cm = 35 cm. Putting ribbons end to end combines their lengths.
5. A broom is about 5 feet tall.
A broom is about as tall as a short adult. Feet is the right unit because inches would need a very large number and yards would be smaller than expected.
6. A TV remote is about 8 inches long.
A TV remote fits in your hand, so we measure it in inches. Eight inches is a little less than a full ruler, which matches the size of most remotes.
7. A garden hose is 50 feet long. That is 600 inches.
To convert feet to inches, multiply by 12 since each foot holds 12 inches. 50 × 12 = 600, so the hose is 600 inches long.
8. A toothbrush is about 18 centimeters long.
A toothbrush is a small personal item about the length of your hand. Centimeters match that size, since 18 cm is close to 7 inches.
9. Two yardsticks end to end measure 6 feet.
Each yardstick is 3 feet long. Two of them end to end makes 3 + 3 = 6 feet total.
