Compare Length in Inches
š Ruler vs. Ruler! Which toy is longer? Sometimes you can't just look at them, you have to measure both and do the math!
Concept
Comparing lengths means looking at two measurements and figuring out the DIFFERENCE between them. šÆ **The "How Much Longer?" Strategy:** **Example:** A toy snake is 12 inches long. A toy spider is 3 inches long. How much longer is the snake? 1. **Measure Both:** We did that! Snake = 12. Spider = 3. 2. **Find the Difference:** "How much longer" ALWAYS means subtraction! (Big number minus Small number). 3. **The Math:** 12 inches - 3 inches = 9 inches. 4. **Answer:** The snake is **9 inches longer** than the spider! *Bonus: The spider is 9 inches shorter than the snake!*
