I can use a number line to solve length problems.
Look: 23 + 18 on a number line
- A toy car is at 23 inches. It rolls 18 inches. Start at 23.
- Hop 10 to 33. Hop 8 to 41.
- 23 + 18 = 41. The car stops at 41 inches.
Draw a number line. Show the hops. Write the answer.
- A frog sits at 16 inches on a tape. It jumps 27 inches forward. Where does it land?Answer: 16 + 27 = 43; at 43 inches
- A beetle is at 64 cm. It crawls back 28 cm. Where is it now?Answer: 64 − 28 = 36; at 36 cm
- A button is at 19 inches. A coin is at 57 inches. How far apart are they?Answer: 57 − 19 = 38; 38 inches
- How far is it from 35 to 62?Answer: 62 − 35 = 27; 27
