This is the home lesson for think like the package, and it's the one method the rest of the program leans on. The single outcome every student must leave with is the reflex to trace a product's ride through a system, out loud, before they draw a line or name a conveyor. If they can repeat the phrase but can't narrate what a carton feels at a transfer, the lesson hasn't landed. Don't teach the question list off a slide. Draw a system on the board and make them ride a box through it.
| Segment | Min | What happens |
|---|---|---|
| Become the package | 5 | Read the hook aloud and have the room close their eyes and become the carton. Put the one idea on the board: the engineer who pictures the product's ride designs for the real world, the one who only draws lines designs for paper. Name the promise of the lesson and keep moving. |
| Narrate the carton's journey | 12 | Key teaching moment, below. Draw a simple three-section system and make a student narrate a package through it out loud. This is the center of the session. Do not read the question list off a slide, pull it out of them at the board. |
| Easy way and hard way | 10 | The two-carton roller demo. Bring props if you have them, a short length of roller conveyor, or even a box and a row of pencils. Turn the same box easy way, then hard way, and let the room watch the support vanish. Land the rule: never fewer than three rollers under the package. |
| The three families and the scope guard | 12 | Cartons, totes, polybags, kept tight. For each one make the room say what the shape actually does at a stop and at a transfer, not just name it. Then the scope guard: specialty handling is a category you recognize here, not one you solve here. That lands in a later lesson. |
| Riverside behavior read | 13 | Round-robin, below. Hand out the four-product table. Each student reads one product like a package and defends the read. Steer the room to the Tall Case on its own. Grade the reasoning, not the label. |
| Forest and close | 8 | Zoom out. One question carries the whole program: what is it like to be the package? Tie it back to the gold banner and send them to write their four Riverside behavior reads into the running note. |
| Total | 60 | Baseline session. Add the stretch below if you have a 90-minute block. |
Go to the whiteboard and draw a simple three-section system: an induction, a curve, and an incline to a mezzanine. Nothing fancy, blocks and lines. Then hand the journey to a student. Tell them they're the carton, they just got set down at induction, and they have to describe out loud what they feel at every transition all the way to the top of the incline.
The moment they can't describe what the package experiences at the transfer or the curve is the moment the design question reveals itself. That gap isn't a student failure, it's the whole lesson made visible. Stop there, ask the room what the box would feel at that exact point, and let them fill it. Do the carton exercise out loud, in class, every time you teach this. It's the center of the session and it doesn't survive being turned into a lecture.
The failure mode this lesson exists to prevent is a student who treats the phrase as a slogan instead of a step-by-step trace. Drive every one of these back to narrating the package's experience at the board:
Hand out the four-product table from the WMS report. Run the behavior read as a round-robin: each student takes one product, reads it like a package rather than a spreadsheet row, and defends the read to the room. No calculator, no numbers. The Standard Case runs easy and gives no trouble. The Small Case is short enough to worry about roller support hard way. The Large Case drives width and curve geometry. The grade is the reasoning, not the label.
The Tall Case is the one that matters here, and you don't hand it to them. It's 10 inches long and 14 inches tall, a narrow base with a high center of gravity, and it's the product you'd flag the second you saw it coming off a second-floor mezzanine. Do not tell them. Ask. Steer the room toward it with questions until a student says it on their own. A student who arrives at the Tall Case through the shape of the box has learned the lesson. One who hears you name it has not. Don't run the decline or the tumble math here, that's a later lesson. Today they only have to feel that this one is trouble.
Question 2 is left open on the student page on purpose. When you debrief it, steer them toward the real questions: what percent of the volume the polybags make up, whether they need to run through the automation at all, and what they do at accumulation and at the sorter. A student who reaches for those on their own has the judgment; one who waits to be told the answer does not.
Keep the Riverside project-note habit alive. Every student writes their four behavior reads into the same running note they started in Part I, dated and organized. Frame it as nothing more than what a professional does.
Here's the part you keep to yourself. The carton exercise you're running today is the exact move the capstone opens with, where the student is told to close their eyes, become a 12-pound carton on the second floor, and trace its journey to the dock before drawing a line. The students who internalize the ride here, and who kept their notes without being told why, are the ones who walk into that moment already fluent. Don't tip the ending. Just make the habit feel normal, and let the payoff be theirs to find.
