| fast / cheap | faster / cheaper | The train is faster than the bus. |
| comfortable | more comfortable | The train is more comfortable. |

How to run Stage 2
5 min: Elicit short comparative forms and check spelling only where it affects accuracy.
Use not as … as for a weaker quality
Both can describe the same relationship. Choose the form that keeps your message natural and avoids repetition.
How to run Stage 3
5 min: Add long and irregular forms, then contrast comparative with not as … as.
Build evidence sentences
- Option A is ______ than Option B because ______.
- Option B is not as ______ as Option A.
- However, Option B is ______ for people who ______.
- My priority is ______, so ______ fits better.
How to run Stage 4
6 min: Build four evidence sentences from the information visual.
Recommend one option
Compare two cafés, transport options, or study plans. Your partner gives one challenge before you make the final choice.
Required: three accurate comparisons, one not as … as sentence, one trade-off, and one evidence-based recommendation.
How to run Stage 5
7 min: Run the comparison and challenge without interruption.
Final practice: Compare two options and recommend one
Task: Give a 60–90 second comparison using three criteria, respond to one challenge, and recommend the option that best matches the stated priority.
Success: The comparisons use matching criteria, comparative forms remain clear, and the recommendation is supported by evidence rather than adjectives alone.
