Name the frame
Is it time, article, preposition, question order, or condition? Naming the frame prevents random guessing.
Grammar lesson
Stop losing points on sentence frames
Grammar improves fastest when the learner stops memorizing rules and starts recognizing the exact frame a sentence wants.
Pressure moment
You know the rule, but the sentence arrives fast and the wrong preposition, tense, or word order comes out automatically.

Mental model
A grammar mistake is usually not one bad word. It is a broken frame. Repair the frame, then swap the content.
Repair sequence
Turn repeated grammar misses into reusable sentence templates.
Lock
Save the full chunk
Keep the corrected sentence as a pattern, not a translation. The chunk is what becomes automatic.
Swap
Change one part only
Replace the noun, verb, or time phrase while keeping the grammar skeleton intact.

Weak
I am looking at my keys.

I am looking for my keys.
