Inventory Basics Slides INVENTORY FIRST
Why checking your parts is the most important single step of any project.
Step 01
Minute Match Challenge
You have 60 seconds. Find the specific bolt your teacher is holding in the box of mixed parts.
Is it easy?
Finding one small part in a mess is hard for your brain.
Is it smart?
Starting a build without all your parts is like baking a cake without flour.
What is Inventory?
1
Identify
Look at the picture in the manual. Name the part.
2
Count
Do you have exactly how many you need?
3
Organize
Put same parts together in their own space.
Save Your Brain
Building is hard. Don't make your brain hunt for parts while it is trying to follow instructions.
"If the parts aren't ready, the brain isn't ready."
The Rule of One
NEVER start Step 1 until you have checked off EVERY part on the inventory list.
Part Match Inventory Log Part Match Inventory Log
Step 0: Verify everything before you start.

Do not begin building yet. Match each physical part in your box to the list below. Place the parts directly on the paper in the "Place Part Here" squares if they fit, or in a neat pile next to it.

Pro Tip:
If you are missing a piece, STOP. Do not try to "make it work." Ask your instructor for the missing component immediately.
Inventory Prep Teacher Guide Teacher Guide
Inventory Prep & Hook
Lesson 01: Setup & Delivery
Learning Objective
Students will isolate the Inventory Phase from the Assembly Phase. By completing a visual check before touching any tools, they reduce working memory load and prevent project-stopping errors later.
Prep Checklist
Assembly Kits (one per student)
One "Mixed Bin" of random parts
Printed Inventory Logs
Timer (60 seconds)
The Hook: The 60-Second Scramble
Before handing out organized kits, gather students around a large bin filled with mixed screws, bolts, and brackets.
The Action:
"I am holding one specific M6 Connector Bolt. I need one student to find its twin in this bin. You have 60 seconds. Ready? Go!"
The Debrief Question:
"Why was that stressful? Now imagine doing that while also trying to figure out where the piece goes in a 20-page instruction book."
Step-by-Step Facilitation
1
Define "Isolating the Step"
Explain that inventory is NOT "starting the project." It is a separate preparation step. Emphasize that jumping ahead to Step 1 without inventory is the #1 cause of failure in fabrication.
2
Visual Matching
Pass out the Part Match Inventory Log . Show students how to compare the physical size of a screw to the drawing on the page. Model "Count Once, Check Once."
3
The "Organized Staging Area"
Instruct students to keep their parts on the inventory log or in separate small containers (egg cartons work well) for the duration of the build. They should not touch them again until the specific instruction calls for it.
Working Memory Supports
For High-Support Needs:
Pre-count parts into small baggies, but still have the student perform the matching and counting on the log to build the habit.
For Extension:
Include "Decoy Parts" in their kit. The student must identify the extra pieces and set them aside as "not part of the inventory."
Fastening Mastery Slides ONE FASTENER
At A Time
The Power of a Finished Connection
Problem Found
The Wobbly Chair Effect
Why do projects fall apart? Usually, because the builder put in all the screws loosely and forgot to go back.
"If it's not tight, it's not done."
The Fastening Process
Phase 1: Hand-Tight
Use your fingers to turn the nut or bolt until it touches the surface. This makes sure you don't cross-thread it!
Phase 2: Tool-Tight
Use the wrench or screwdriver. Turn until it is firm.
This is the single step most people skip.
Close the Loop
Don't let your brain "plan" for the next screw until the current screw is 100% finished.
New Habit:
SCREW -> TIGHTEN -> CHECK
Your Mission
Complete your Connection Check Tracker. You cannot move to the next part until you have physically checked off the "Tightness Test" for the current bolt.
Follow the Tracker

The Goal
The Golden Rule: Do not start Screw #2 until Screw #1 is Tool-Tight and you have checked the box. A "loose" build is a "failed" build.

Fastening Rubric Demo Guide Instructional Guide
Fastening Mastery
Lesson 02: One Fastener at a Time
The Hook: The Wobbly Chair Demo
You will need a small chair or stool with the fasteners halfway loosened.
The Action
Place the chair in the center of the room. Ask a student to sit on it (carefully!). The chair will wobble or lean dangerously.
The Insight
"The person who built this put EVERY screw in, but they didn't FINISH any of them. Rushing to the end makes the whole project a fail."
Fastening Quality Rubric
Level Visual Indicator Physical Test Feedback String 1: Loose Gaps visible between nut/bolt and surface. Part rattles or rotates freely by hand. "Step not closed. Apply tool." 2: Hand-Tight Bolt head is touching the surface. Part is held in place but will shift with force. "Good start. Finalize with tool." 3: Mastery Flush fit. No gaps. Surface may slightly compress. Zero movement. "The Wiggle Test" passes. "Connection Locked. Move to next."
Teaching the "Tool Transition"
Students with working memory needs often forget why they are holding a tool. Instruction: Tell them to put the tool DOWN between screws.
1. Pick up screw. 2. Hand-thread. 3. Pick up tool. 4. Tighten. 5. Put tool down.
Spatial Support Tip
Use color-coded stickers on the assembly project (e.g., a green dot next to the first screw hole, a blue dot next to the second). This anchors their attention to the Current Task only.
Circulation Checklist
Is the student checking off the tracker in real-time?
Are they skipping hand-tightening? (Risk of cross-threading)
Is the tool being put down between steps?
Are they performing a physical "Wiggle Test"?
Partner System Slides BRAIN & HANDS
The Stop-Check-Go Partner System
The Tied Challenge
The Problem
If you are physically tied to your partner, you must move together. You cannot rush ahead because your partner is literally holding you back.
The Lesson
In assembly, the instructions should hold you back just like that rope. Don't move until the instructions say "GO."
Assign Your Roles
THE BRAIN
• Only one touching the book
• Reads the step out loud
• Decides when to "STOP" or "GO"
THE HANDS
• Only one touching the tools
• Listens to instructions
• Shows the work to the "Brain"
The Protocol
STOP
Brain reads step. Hands find parts.
CHECK
Hands perform step. Brain inspects it.
GO
Brain turns the page. Repeat.
Speak It Out Loud
"The Hands" cannot touch anything until "The Brain" says
Stop Check Go Cards Partner Role Communication Cards

I am the ONLY person who reads the book.
I INSPECT the work before turning the page.
What I Say:
"Step #____ is finished. I have verified it. Proceed to Step #____."
Role B
THE HANDS
Lead Fabrication Engineer
I am the ONLY person who touches the tools.
I WAIT for the verbal command to move.
What I Say:
"Parts for Step #____ are ready. Please inspect the connection."

Partner Facilitation Plan Partner Facilitation
Lesson 03: The Stop-Check-Go System
Teacher Guide
The Hook
The "Hands-Tied" Challenge
Students are often resistant to partner roles because they want to "just do it." This hook creates a physical consequence for rushing.
Instruction:
"For this activity, you are physically tied to your partner's wrist with a short piece of rope or a zip-tie (loose). Your goal is to move a stack of 10 nuts from point A to point B. If the rope goes tight, you have to start over."
The Takeaway:
Success depends on matching the speed of the slowest person. In assembly, we must match the speed of the instructions.
Facilitation Steps
1
Strict Resource Control
Give the Instruction Manual only to 'The Brain' and the Toolkit only to 'The Hands.' If you see 'The Hands' looking at the book, pause the project.
2
Verbal Sign-Off
Walk around and listen for the scripts on the Stop-Check-Go Cards . Students should not proceed until they hear the specific "Locked Connection" confirmation from their partner.
3
Role Swapping
Halfway through the build, force a role swap. This helps students experience both the cognitive load of reading and the physical precision of building.
Reflection Prompts
Question 1:
"Which role was harder for your brain? Remembering what to do (Brain) or doing it perfectly (Hands)?"
Question 2:
"Did having a partner make you go faster or slower? Why is slow and correct better than fast and wrong?"
Conflict Management
If partners are arguing or one is dominating, introduce the "3-Second Rule": The Brain must wait 3 seconds after the Hands finishes a step before speaking the next instruction. This enforces the "Check" phase.
Orientation Mastery Slides WHICH WAY?
The Mental Step of Checking Orientation
Building in the Dark
Have you ever tried to put a key into a lock when it's dark? You have the right part. You have the right hole. But it won't fit.
Orientation is the direction the part is facing.
One Detail Changes Everything
PART A
Hole is UP
PART B
Hole is DOWN
If the manual says Part A and you use Part B, Step 10 will be impossible.
The 3-Point Check
HOLES
Are they facing the right way?
EDGES
Is it flush or overlapping?
SLOTS
Are the grooves lined up?

"I knew it was correct because the hole was on the ______ side."
Orientation Scavenger Hunt Guide Spatial Reasoning Resource
Orientation Scavenger Hunt
Lesson 04: Visualizing Orientation
Activity Goal
Before students touch their actual kits, they must identify the "front," "back," "top," and "bottom" of three common objects in the room. This builds the mental habit of Checking Orientation First.
Teacher Setup
Identify 3 objects (e.g., Chair, Tablet, Drawer).
Place a small piece of blue tape on the "Front" of each.
Have students find the tape and explain why it's the front.
Student Observation Checklist
Physical Rotation
Does the student physically rotate the part to match the picture in the manual?
Detail Identification
Can the student point out a specific detail (like a pilot hole or a groove) that indicates direction?
Comparison Check
Does the student look back at the manual AFTER the part is in their hand to verify its orientation?
Common Misconception: "It looks the same."
Many students struggle with mirroring. They may think the part is correct if it has the right shape, ignoring the direction of the holes.
Instructional Cue: Ask them, "If I flip this over, does it change where the hole is?" Physically flip the part to demonstrate.
