Assemble and report
Show on a big screenThe four jobs exist. Running them in the right order is a job of its own. Each job reads what the job before it wrote. Then it passes its own answer to the next job. A tally is a count for each word.
- Two ways to run the same four jobs.
- In order — collect, decide, order, report — the sheet lists every kite.
- Tally: steady 2 of 5, dancer 3 of 5.
- Out of order — report runs before collect has gathered anything.
- The sheet lists 0 kites. Tally: 0 of 0. Each job works, but the order is wrong.
The rule
Collect, decide, order, report — the order matters. A job run too early has nothing to work on. The sheet shows exactly what the order produced.
Run in order, the check-in list becomes today's sheet, shortest tail first:
| Kite | Span | Tail | Word |
|---|---|---|---|
| A1 | 3 | 4 | steady |
| A2 | 8 | 4 | dancer |
| A4 | 2 | 7 | steady |
| A3 | 9 | 8 | dancer |
| A5 | 7 | 11 | dancer |
Tally: steady 2 of 5, dancer 3 of 5.
Kites A1 and A2 both have a tail of 4. The sort swaps two kites only for a strictly shorter tail. A2's tail is not shorter than A1's, so there is no swap. A1 stays ahead of A2. No kite after them has a shorter tail.
Tap the four jobs in order. Then tap them in another order.

Every card really runs its job. Each job runs on the check-in list and register you already checked.
