Your chosen sheets
Name the sheets you decided to cover, and why you chose them over the others.
Before you name your sheets, remember the constraint.
1. Why can't you cover every sheet in your 90-second recording?
What the recording has to do
Assessment criteria
| Criterion | What it means | Weight |
|---|---|---|
| Structure | Sheets covered in order, using ordinals and sheet numbers correctly | 25% |
| Precision | At least one exact dimension and one precise location, no vague directions | 30% |
| Fluency | Numbers and question forms said without visible hesitation | 25% |
| Fit | Everything genuinely fits inside ninety seconds | 20% |
The fit criterion is a real constraint, not a formality. Choosing what to leave out is as much a skill here as saying what stays in — a walkthrough that runs long because it tries to cover everything says less clearly than one that picks three sheets and covers them well.
Match each criterion to what it actually means.
Plan the ninety seconds
Before recording, write down:
- The sheets you will cover, in order, and roughly how many seconds each gets
- The one exact dimension you will read aloud
- The one precise location you will give — sheet and position
- A question-and-answer pair you can work in naturally
Put these four planning notes in the order you will write them down.
Record the walkthrough
One check before you press record.
1. If you run over ninety seconds, what should you do?
Portfolio piece 2 of 10
Your own sheet index · 90 seconds · recorded
Record the walkthrough you would actually send someone who needs to know your set fast.
- Ninety seconds. Time it before you call it done.
- At least one exact dimension, one precise location, one question-and-answer pair.
- Re-record if you run over — cutting it in editing is not the same skill as choosing what to say.
Lesson 1, revisited
Compare today’s recording to your Lesson 1 baseline and answer:
- Did Lesson 1 use sheet numbers and ordinals, or only description?
- Were your dimensions correct in Lesson 1? Are they now?
- Would a stranger have been able to find a specific sheet from Lesson 1 alone?
A final check on the unit. Each sentence has one error.
1. The wall is fifty-two feet six.
2. Which sheet the drainage plan shows?
3. It's over there somewhere.
Unit 2 complete
You can now: navigate an unfamiliar sheet index using the fixed convention, ask and answer "which sheet / where" questions in natural word order, read feet-and-inches dimensions aloud without translating, and give a location precise enough for someone who cannot see your screen. That is the B1 can-do statement for this unit, and it is signed off.
Next unit: materials and methods — naming and comparing materials, and explaining a construction assembly step by step.
Homework before Unit 3. Find one construction detail on your own drawings — any assembly, wall or deck. Be ready to describe what it is made of, even informally.
Last check of the unit.
1. What should you bring for Unit 3?
