Blueprint calculations are examples of what Real Trades Math questions are: a list of step to answer a simple question, with a simple answer. But following the steps requires proficiency with several math skills, in this case:
We will also investigate Unit Conversions, Metric and American, as time permits.

I will monitor ask me if you have any questions about the midterm.
@sunset, i retire to my cabin, wonder what went well, and not, that day. resting in my hammock, i consider my best tack forward at daybreak: push the homework deadline forward. My bones creek with the ubercrawl’s.
my last orders were not entirely executed. Nail Penetration and Screw Holes are still out there. it was Friday, we were all tired (at least your projected Zoom rectangles on my dark wall were), i made a judgment call on the fly: instead of taking breaks in the shanties, i gave not 1, but 2 breaks in the main hull. so we’re still behind the course i plotted last week.
My biggest takeaway from the last class was the unwillingness of some of our crew to submit anything less than a perfect product. The trades is more about managing your time, than producing perfection. There will always be a crew following you to do your touchups.
Second was the affirmation that it looks easy when i dance my ditties, but when you have to do it yourself, you best been taking good notes.
Finally, everyone on the ubercrawl, right now, surely must know what a Kwik/z is: instant feedback. If not, click here. Today’s Kwik/z will be on Nail Penetration and Screw Bits.
TAKE GOOD NOTES!
DEADLINES WILL BE STRICTLY ENFORCED!
Here’s what we’re doing today:
It is likely we will run short today. If so, I will begin Green Math, but it will NOT be on the midterm.
Last class, I spoke too much. Today, three times over, I will give you an instruction, you will crew up, enter the shanties, and produce a product, in a timely fashion. We will cover three topics today, so the only time for breaks today will be in the shanties, when your crewmates can cover you.
Here are today’s topics:
lots of action ready to go
Welcome GCP 04-22! Our launch today is my last voyage captaining a 2021 worker education class, making me un peu pensive.
Why I chose a career in worker education is that I despise cubicles. For the last decade, I have been in classrooms where most of us felt the same. A couple of months after COVID hit, under duress, I set sail aboard a raft I named the ubercrawl with BCP 134.
Unlike most experiences my colleagues suffered, trades math, instilled with labor traditions, shone bright as my lodestar. Every iteration, every upgrade, my raft evolved into the battleship we now crew.
No matter what happens next year and beyond, I know my starry ship will be retired. Which make this voyage, for me, rather poignant.
I hear good things about your crew, and will make an exception to my ship’s rules, a query: what would you like to learn about green trades math? Please post a reply, as a comment, below.
Here’s what we’re going to do today:
First, we will look at percentage problems. Then, we will apply percentages to a common application in the trades: tolerance. When you buy a box of nails that says it has 200 in the box, and it actually has 201 or 199 nails, the tolerance is ±1 nail. For resistors, tolerance is expressed as a percentage.
Calculating a resistor’s tolerance is another 3 step process:
Let’s practice some more …
