- 3 Keep every factual detail from the original recipe. Do not drop steps or items.
- 4 Earn 1 bonus point for each Unit vocabulary word incorporated accurately into your lines.
- 5 Read your final recipe aloud to the class; the smoothest, clearest text wins!

Original Text Card
Corner Jar Recipe (invented).
Six lines that each start with new information.
Original Clunky Draft (New information piled at the start):
A cook scrubs some carrots and cuts them into thin sticks.
A clean glass jar holds the sticks, packed in tightly.
A little salt stirred into cold water makes a brine that covers the sticks.
A loose lid goes on top of the jar so that the gas can escape.
Tiny bubbles and a sour smell show up after a few days in a warm room.
A cold fridge slows the process once the carrots taste sour enough.
Doctor's Guidance Card
Test Card
The Golden Question
Test card: Which words did an earlier line already give me? Start with them; put the new information last.
Step A: Diagnose
Spot the anchor word from the previous sentence (e.g. sticks, jar).
Step B: Shift Weight
Use the passive or "It is ... that ..." to move new details to the end.
💡 C1 Pro-Tip: Putting new information last helps listeners follow a long set of instructions.
Team Rewrite Sheet
Line 1 is fixed. Perform surgery on lines 2 through 6. Ensure each starts with known information and carries every original fact smoothly.
Scoring Rubric
Starts with Known Info
The sentence subject anchors to something established in the preceding line (up to 5 pts).
Retains All Info
Every measurement, qualifier, and condition from the original draft is kept intact (up to 5 pts).
Food Science Vocabulary
Each distinct Unit word used accurately in your rewritten lines grants 1 extra bonus point.
Eligible Unit Words for Bonus Points (1 bonus per different word):
Sentence Starters
"The sticks are then packed into..."
Maintains carrot sticks as topic subject without repeating the cook.
"These sticks are covered with brine, which is..."
Connects the familiar vegetable to the newly defined salty solution.
"It is with a loose lid that the jar is fitted..."
Directs emphasis to the container closure while allowing gas escape.
"Once placed in a warm room, the jar..."
Carries the vessel forward while introducing the warm place.
"What develops inside the jar is a sour smell..."
Signals active microbial growth and rising acidity.
"To prevent spoilage once the sourness peaks, the jar..."
Shifts the preservation goal to front position before naming the cold fridge.
Teacher Key & Model Answers
Model Line 2:
The sticks are packed tightly into a clean glass jar.
Model Line 3:
The sticks are covered with brine, which is a little salt stirred into cold water.
Model Line 4:
The jar is closed with a loose lid so that the gas can escape.
Model Line 5:
The jar is left in a warm room, and after a few days tiny bubbles and a sour smell appear.
Model Line 6:
The jar then goes into a cold fridge, which slows the process once the carrots taste sour enough.
Variations
Link Hunting
Give teams highlighters to underline the known link word in each original sentence before attempting any rewrite.
Passive Lockdown
Every rewritten line must be passive, so the thing we are talking about stays at the front.
Cleft Surgery
Use at least two sentences that start "It is ... that ..." (for example, "It is into a clean jar that ...") across the recipe.
Vinegar Pickling
Hand fast teams a 3-line vinegar-pickle process with clunky beginnings and challenge them to perform instant oral surgery.
Closing Questions
The Reading Rhythm Test
How did reading the rewritten recipe aloud feel compared to the original clunky version? Why did your breath and pacing change?
The Listener's Brain
