I've always been confused by how this is meant to help - could you explain further? I've always been a technical founder, but I've never had any idea how to find a technical co-founder - as you correctly say, good technical people will have their idea they're excited about! So I'm always skeptical that "make a prototype" would work to convince anyone, but perhaps it would - is there some hidden pool of good engineers who exist in some weird fugue state of "show me a cool semi-working website and I'm on-board", outside of, like, 1st year CS?
We studied a lot of fractions, decimals, percentages & converting between them. There was a bit of angle stuff mixed in there, too.
I love mathematics, so I think I'd be the sort of teacher you could see eye-to-eye with. What should I be doing differently?
Lots of people can read minds. Not literally, of course, but they've put in the work (and perhaps it was work that they found easy and pleasant, much as many programmers found math) to be able to essentially tell what people want, don't want, are implying, will be offended by, etc. Yet I've certainly heard plenty of people, and especially STEM-types, making a point of pride about lacking this skill: "I'm a straight-shooter" and the like. There's aspergers and there's dyscalculia, but many STEM types who happily admit to lacking this skill are just like those whom the author bemoans - they find it difficult and uninteresting. And that's okay! But it's no truer, really, than "I can't do maths".
As a former teacher, here is an example lesson plan:
AGE GROUP: Year 5 TOPIC: Introducing prime numbers
STARTER: Mixed multiplication table questions on board. MAIN ACTIVITY: Write the number 92 on the board. Ask students whether '92' appears in any multiplication table. When the answer '2' is received, stress that multiplication tables do not end at 10 or 12, but continue on indefinitely. Repeat for the numbers '999', '186', and '495'. Next, write the number 71 on the board. Students will conclude that it does not appear in any 'tables'. Explain that it does, offering a reward for the first correct answer. With or without hinting, get the answer '1' or '71'. Offering a second reward, get the second of the pair. Explain that every whole number is in the 'one' times table and the 'itself' times table. However, such numbers are called 'prime' if those are the only ones. Ask students to name other prime numbers below 50, discussing suggestions.
Complete is_it_prime.doc. Students who finish quickly should attempt is_it_prime_2.doc.
That's not meant to be particularly inspiring or anything, just representative. As a teacher, you have a legal obligation to have such a plan for every lesson you teach (this was true in the UK, can't speak for other countries).
