30-minute lesson route
Choose fair comparison criteria

Use two real options and three qualities that apply to both. A useful comparison answers a decision need rather than listing random adjectives.
How to run Stage 1
3 min: Choose two real options and three fair criteria.
Build common -er forms
fast → faster, cheap → cheaper, large → larger, big → bigger, easy → easier. Use than before the second option when it is named.
How to run Stage 2
5 min: Build common -er spelling patterns.
Use more and useful irregular forms
Engduo Audio: Listen for meaning first. Audio never starts automatically.
Listen for three criteria and the reason for the choice.
Track the short, longer, and irregular comparative forms.
Use more with many longer adjectives: more convenient, more comfortable. Learn useful irregular forms as complete items: good → better, bad → worse.
How to run Stage 3
5 min: Add more comparatives and better/worse.
Match each criterion to the winner
Listen to both comparisons. Complete a three-criterion table and identify the final need that determines the choice.
How to run Stage 4
6 min: Play both models and complete the criterion table.
Compare two options and choose
Compare two options across three relevant criteria. Use at least two -er forms, one more form, and one reason explaining which option better fits the stated need.
How to run Stage 5
7 min: Compare three criteria and justify one choice.
Final practice: Compare two options and justify one choice
Task: Compare two options across three criteria using at least two -er forms, one more form, and three than comparisons. Choose one option for a stated need and justify it.
Success: Comparative forms are accurate enough, criteria remain relevant, and the learner makes a clear evidence-based choice independently.
