Comparison vocabulary
- Longer / shorter — direct, side-by-side comparison.
- Same length — they line up exactly.
- Twice as long — one fits into the other exactly two times.
- Three times as long — three of the short one equal one long one.
Your turn
Ribbon A is 18 cm, ribbon B is 6 cm. How many times longer is A?
