Math would be a lot funnier if we allowed sets to have more than one median. Do you know why? Because they'd be called co-medians!

Teachers… what would you say is your ultimate goal for students?

[Chad Lang, Ed.D. @Chad_mLang]

Love this point on the new @Assess_THAT episode quoting @leeannjung, "Formality is not akin to validity."

Important to ponder for those who automatically trust curricular resource canned assessments over their own assessment architecture.

@pwharris For both fractions there is a difference of 5 between the num are denom. the 5 units in the 6/11ths is smaller than the 5 units in the 4/9 because of the size of the cuts (denom) which means 6/11 is greater since 6 is closer to 11.

Loved being with these brilliant Grade 2s and 3s who were so engaged in BTC. Loving the K-5 book! Can you guess the task? @MaeganGiroux @pgliljedahl @MackenzieGlenPS

When…. WHEN will we stop labeling other ppls babies?! We would NEVER call our own kids “low kids” or “iep kids.”

It seems small, but LANGUAGE matters. It impacts how we show up for kids.

Get familiar with the mesmerizing math art of MoMath’s Visiting Professor David Reimann (@drMathArt), like these representations of integers 1-100.

What are some patterns you notice?

I wish I was taught this way of finding the greatest common factor when I was in school

[natalie cogan @NatalieCogan]

@howie_hua 4 groups of 25 is 100. So 12 groups (triple-triple) is 300. 25 makes me think quarters.

Do you know why a negative divided by a negative equals a positive? If not, find out in 40 seconds.

[natalie cogan @NatalieCogan]

@howie_hua I’d do 240 + 120 so times 10 and times half of that put it together for 360

[natalie cogan @NatalieCogan]

@pwharris This from my grade 5 daughter.
200 + 200 = 400
40 + 50 = 90
9 + 2 = 11
90 + 10 = 100
100 + 400 + 1 = 501

me:
250 + 251
250 + 250 + 1 = 501

Are your ss struggling w/math facts? @JBayWilliams reveals we need to build on ss strengths. Ss need explicit strategy instruction which is NOT the same as direct instruction & practice should be centered around choosing/using strategies, not drill and kill. #NCTMDC23

@howie_hua Eliminate 1/4 by making it 5 - 2 1/2.

@DodaroMrs Love this one!
