@pwharris So I think of a box of donuts and visualize two of the three rows - and since each row has 4, that’s 8 donuts! 🍩🍩

[Dr. Joseph Bolz, NBCT @JosephBolz]

@keyhyers Thanks! And thanks for being there!

[Dr. Joseph Bolz, NBCT @JosephBolz]

Looking for BOOK suggestions - both fiction and Math/Education books. Drop me your best suggestions!

ICYMI 👉 We are hosting a webinar on #selfcare for teachers: https://t.co/NQdL8SatE5

Presenter @JosephBolz will walk through practical solutions to combat teacher burnout and understand the “why” behind some of these strategies.

This webinar is exclusive to NCTM members.

[Dr. Joseph Bolz, NBCT @JosephBolz]

@tetzloffski Thanks that means a ton!

[Dr. Joseph Bolz, NBCT @JosephBolz]

@ezdailyquiz I’d love to see you put this problem in a real world context. And go…

[Dr. Joseph Bolz, NBCT @JosephBolz]

@BradBMath @pwharris The Brad B Theorem - Given a x b, if we find c and d such that c and d are equidistant (in opposite directions) of a and b respectively, a x b = c x d - c and d’s distance from their midpoint squared plus the distance of a and b from that same midpoint squared

[Dr. Joseph Bolz, NBCT @JosephBolz]

@BradBMath @pwharris = cd + (a - c)(d - a)
= cd + ad - a^2 - cd + ca
= a(d + c - a)
= a(a + b - a)
= ab

So yeah - we just proved this method worked!

@howie_hua 1% of 45 is 0.45
2% of 45 is 0.90
12% is 6 times 2% so
12% of 45 is 5.4

What brings you joy as a teacher?

[Dr. Joseph Bolz, NBCT @JosephBolz]

So I asked my kids what it really equaled and they had some great ways to figure this out!

How would you solve it? Share your thinking!

[Dr. Joseph Bolz, NBCT @JosephBolz]

@teacher2teacher I do all the math problems I expect my students to do that day - I like doing the math and it also helps me think like the students! No matter the level or how many times I’ve done them….

[Dr. Joseph Bolz, NBCT @JosephBolz]

@MathsCirclesOz The solutions to any equation of the form x^n = a + bi graph a regular polygon with n-sides on the complex plane - there’s something so awe inspiring when I get to show that to my students

[Dr. Joseph Bolz, NBCT @JosephBolz]

@howie_hua One gym plate is 45lbs
Two gym plates are 90lbs
Eight gym plates are 360lbs
(Ok I can do this without the middle step but showing the thinking for all).

If each plate is 45 lbs, that’s three 15s. This means that eight 45lb plates is the same as twenty-four 15lb plates.

So 24!

Them: How long have you been teaching?

Subs in my first year: Ok class, Mr Bolz is out today. He asked you watch this movie…

[Dr. Joseph Bolz, NBCT @JosephBolz]

@pwharris I grew up on video games and arcades so I know that 36 quarters is $9.

That means 35 quarters is $8.75.

So if we do 25x35 we get 875!

Thank you Pac-Man and DigDug!
