Length word problems involve understanding and comparing different lengths. In second grade, this often means adding or subtracting lengths given in the same units (like inches or centimeters) to solve real-world problems. It's all about figuring out how much longer, shorter, or the total length of objects are!
Let's practice with some exercises!
Match the term with its definition:
| Term | Definition |
|---|---|
| 1. Length | A. The distance from end to end. |
| 2. Unit | B. A standard quantity used for measurement (e.g., inch, centimeter). |
| 3. Measure | C. To find the size, quantity, or amount of something. |
| 4. Compare | D. To examine the similarities or differences between two or more things. |
| 5. Estimate | E. To make an approximate calculation or judgment of a value. |
