It's a tragedy when any child is killed but denying facts to further your narrative is destroying this nation and must be challenged EVERY TIME.https://www.snopes.com/fact-check/have-undocumented-killed-63000-us-9-11/ …

@dmarain After students have been exposed to some combinatorial thinking some might ask if the formula 3•C(4,2) works! Generalizable? I'm very sure that you could share several other strategies!

@dmarain This "simple" problem is accessible to all but more importantly shows that mathematics is truly a way of thinking. Systematic counting/combinatorics reveal the underlying beauty of this question.#MTBoS@jamestanton@HarMath@johnjoy1966@mrdardy#mathisfun#mathschatpic.twitter.com/TpOzblyw05

@dmarain Not a mathematical fact about zero but I am also curious about people whose names are Zero like Zero Mostel. But also this...pic.twitter.com/eqrkccZaoK

@dmarain ONE may be the loneliest number but Zero has self-esteem issues too! Pls reply with 2^0 math fact about 0 to cheer it up. By the way I encourage parents and teachers of young children to consider the book below...#MTBoS@HarMath@jamestanton@johnjoy1966@mrdardypic.twitter.com/8jPkeWv3de

@dmarain Asked 12- & a 22-yr old if more #'s betw 0 & 1 or more #'s > 1 & why. One said, "betw", the other "greater". Yes, I was purposely vague and omitted "same amount". Guess who picked what and why! Comments? Pls RT if you like.#MTBoS@jamestanton@HarMath@johnjoy1966Hvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -

@dmarain This tweet will be expanded later on my blog MathNotations! http://mathnotations.blogspot.com/?m=1 I chose a well-known problem about sum_product of 2 #'s to focus on the art and science of developing conceptual reasoning.@HarMath#MtBos@jamestantonPrikaži ovu nitHvala.

@dmarain Sum of 3 & 2? Product? "The prod of 2 numbers is always greater than their sum" Ex that support; contradict Revise Conjecture. So 2,2 and 0,0 are only prs that make =? Discuss! Check 3 and 1.4? Ideas?#MtBos@jamestanton@HarMathPrikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -

@dmarain Presh Talwalkar's outstanding YouTube channel "MindYourDecisions" uses technology and brilliantly lucid explanations.

@dmarain 7^3-3^5=100 Let's check this by overcomplication! 7^3-3^5=[3•(2+1/3)]³-3^5 =3³(2+1/3)³-3^5 = 3³[(2+1/3)³-3²] 27[2³+3•2²•(1/3)¹+3•2¹(1/3)²+(1/3)³ -9] = 27[8+4+2/3-9] =27(3+2/3)=82+19=100 Pure silliness? Now use logs!

@dmarain@senatemajldr In order for the American people to believe that justice has been served and there is no cover-up, I strongly urge you to open up the Senate trial to the public via CNBC.

@dmarain If you feel that some of my problems are unrealistic for the ages listed, I've used similar problems in classes over 40 years. I adapted them for each group but I never said to myself that this is too much of a stretch. Developing minds require extending their reach!Prikaži ovu nitHvala.

@dmarain What skills needed for... Define G as 1 followed by 100 zeros (A) Write G as a power of 10; 100; 100000 (B) G+G= (I) 10^200? (II) 20^100? (III) 2•10^100? (C) Write as a power of 10: G+G+...+G I. 100 terms II. 1000 terms III. G terms@jamestanton#MTBoS@HarMathPrikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte.

@dmarain Interesting perspective. Coding can be taught very early, however it doesn't replace basic skill-building and other math content. But it does strongly complement curriculum and is highly motivational!@HarMath#MTBoS@jamestanton#mathschat#math@johnjoy1966Hvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte.
