5 Ways to Encourage Deep Mathematical Thinking
You can adapt the curriculum you have to create rich tasks that invite reasoning and build students’ problem-solving skills. By Jo Boaler #MathChat

Why Teaching is Harder When the Math is Easier - Dan Meyer
From Dan: "I need new ideas for doing conceptual work at classroom scale."

From me: Me, too! Excellent computer simulations make guess & check too much fun so there's little if any Mathing!! #iTeachMath #MathChat

The TI-34 is a fairly basic scientific #calculator. I’m a big fan because it’s easy to use and not overwhelming.

I was reading the manual and discovered it has two functions:

ipart(x)
fpart(x)

These return the integer and fraction parts of x.

ipart(2.34)=2
fpart(2.34)=.34

Great! So, uh.. What are these typically used for? Why include them on such a *basic* calculator? #calculators #ticalc #ti34 #matheducation #mathchat

Here's the December Calendar of Problems from 40 years ago... the first year of the calendar format!!

Enjoy #ProblemSolving this month yourself or w/students; share thinking here or on the post.

Curious what my mathematician & math educator friends think of the use of AND on this sign...
Wondering if dogs OR alcohol are allowed on the beach, just not at the same time?

To The Erudite In Mathematics Who Wish To Remove Infinity (∞)

An axiom of which we are all conscious: the acknowledgement of the unknown.

The symbol of Infinity is the mathematical constant that, through its own logic and reason, grants us the ability to formulate useful formulae. It demarcates a value that is unknown, yet undeniably present.

Someone has pointed out, quite rightly, that I really should tag @standupmaths when I mention a video that he has made.

I'm not sure appearing in a video counts as a connection for an Erdős number, much as people might hope it might.

So ... the monostable (or self-righting) tetrahedron:

A new video from Matt Parker:

And I'm in it !!

Don't let that put you off ... the rest of it is pretty good.

What hashtags should I use?

School math was originally grounded in what was needed for successfully navigating business and commerce. #math #maths #mathchat

Why do people who are clearly quantitative thinkers and competent at computing become so apologetic and dismissive about the #math abilities? Maybe it time we seriously rethink the damage done in mathematics #education. #mathchat #maths

Jean Lave described how “success in school math” does not predict “success using math in real life.” #math #maths #edchat #mathchat
