Mr. Lower

@ELmagazine @DillinRandolph Dillin, curious to know your thoughts on similarities (if any) to Webster's attempt to change British English to American English shortly after the Revolutionary War. (Here is one of many articles I found about it: mentalfloss.com/article/65791/…)

Twitter, we need your help! We have an idea for @cheezit but they cannot accept confidential ideas, so we have to make it public. Check out the thread and let them know that you want to live in a world where mathematical CHEEZ-ITS exist. 📢

@GlobalMathDept Is there a Webinar right now? I am trying to attend, but it says it is over.

My name is going to Mars. How about yours? Deadline Closing for Names to Fly on NASA's Next Mars Rover jpl.nasa.gov/news/news.php?…

@MT_at_NCTM A6 The value of "a" telling us if the graph opens up or down. And the incorrect assumption that if a is positive, then we have a maximum. #MTChat

Q6. What are other aspects of equations and corresponding graphs students struggle to connect? What are your strategies? #MTChat

@WeaverPower177 @MT_at_NCTM I agree that technology can sometimes get in the way of comprehension. Somewhat assuming that we already talked about the discriminant and they know what that is/means and can calculate it by itself. #MTChat

@MT_at_NCTM A5. That's difficult... sometimes technology leads to understanding and sometimes it never allows full comprehension because no "brain work" was done. #MTchat

Q5. During the second activity, when would you have students compute √(b2 – 4ac)/2a by hand and when would you let them use technology? #MTChat

@MT_at_NCTM A5. But if they are comfortable with Order of Operations, then I would let them use a calculator right away. I'm not teaching that skill at the moment. #MTChat

@MT_at_NCTM A5. Well, I would have the 2a in parentheses in the denominator so they don't do divide by 2 then times a (which is the Order of Operation rule) :) #MTChat

@bridgetdruken I mean, I did see it in the image, but too long to type. (Sorry again). #MTchat

@bridgetdruken Aw man, did you post the link to the article earlier? I was looking for it, but didn't find it, so was participating "blind" tonight. Sorry. #MTchat

A3 looking at the first and last terms, they sum to 90, the next two terms in sum to -90 (so they add to zero). Continuing the patter, I see another 90 and -90. That leaves 45 in the middle as the only thing to keep. #mtchat

Responsibilities of an Educator chadtlowermath.wordpress.com/2018/12/19/res…

@MT_at_NCTM A4 #MTchat I think the preparation has to start at the beginning of the year. Encouraging mistakes and thinking out loud, among other behaviors.

Q4 How do you prepare to teach lessons through problem solving in a way that makes the challenges productive for student learning? #MTchat

@MT_at_NCTM A1 #MTChat I used a formula to describe the number of gray and white tiles, and then set them equal. m = length and n = width to start.

Q1 When first reading the border problem in the article how did you consider solving it? Did it differ from a shared solution? #MTchat

@MT_at_NCTM I a not a Twitter expert. How do you make it "live?"

Here are a few tips to help you get the most out of this #MTchat:
