Dad, husband, math teacher, investor, 🇨🇦/🇺🇸, I’ll forever call it Twitter.

@howie_hua 2/7 is between 2/8 and 2/6

[Redstone @MarkRed78]

@howie_hua 320/8 + 40/8 = 45

@KayleeeMca @Timodc Go watch Kid Rock on the other channel.

@Tyland748957 @fcpsnews Nobody wants kids to get hurt, that’s not my point. The kids are missing out on their education; the curriculum doesn’t change due to weather, and now teachers will have to rush topics or skip them.

It has been a week. Fairfax County should have addressed snow removal by now!!

@howie_hua Brian Johnson and Bon Scott both preferred AC^2/D.

@MrsEppsMath 45^2 👌

@samstein His motorcade passed me heading west on the Dulles toll road Sunday morning, on his way to solve all our foreign and domestic woes.

I mean, to golf at taxpayer expense.

@grsmith2008 @samstein I was just about to post this! 😅

@JessicaTarlov @Timodc Russia could walk into any European country he wants to, and the idea that he’d honor article 5 is beyond laughable.

@fcpsnews Parents are pleased; high school students on Twitter are…upset 😅

[Redstone @MarkRed78]

@howie_hua @TimBrzezinski 87.5% is 7/8th; 7/8 of 80 is 70

[Redstone @MarkRed78]

@Acyn This for sure totally happened, and isn’t made up at all. Sounds exactly like the words @JustinTrudeau would use in such a conversation.

[Redstone @MarkRed78]

@howie_hua Instead of 8x+13y=130, use the equivalent y=-8/13x + 10.

The x-intercept of this function is 16.25; any input greater than this, results in a negative value of y.

X needs to be a multiple of 13, otherwise the product of -8/13 yields a fraction.

For x=13, has y=2.

[Redstone @MarkRed78]

@howie_hua Commutative property for the win…
5+5+5+9+9
15 + 18 = 33

[Redstone @MarkRed78]

@BurnsideMath Great way to relieve test anxiety, and demonstrate that student discourse is valued. 👍🏻

[Redstone @MarkRed78]

@howie_hua That’s a lot of negativity towards timed tests, despite the selection bias!

Quick recall is important, otherwise kids struggle as topics get more involved.

As a parent of a 1st grader, I’m open to alternatives; if we value speed/accuracy, how else can we assess basic facts?

@POMS_Principal @pinoakms @PinOakPTO @HISD_West_D1 @jrv206 @HoustonISD @ashly_vining @jeremyatschool @CatoniOlga @MadamPrincipal4 Look out, world!

Here's a great summary of the case for making all K-12 schools phone-free. Like me, the author could not find any serious arguments, laid out in writing, for the other side.

Phones in hands and pockets interfere with just about every goal of education

@Laughteris85747 @houstonisdwatch @KHOU @houston_tsta @TxEdHouston @HoustonChron @BuildUpHISD @HFT2415 @HISD_Outreach @HISD_Insider Typo aside, that’s just lazy formatting. The 10’s are different sizes. Next, why present kids with those answer choices? They may choose to decompose the 13 into 6 and 7 (sure, maybe it’s not as obvious as 10+3). Different approaches can lead to more productive discourse.
