The standard algorithms certainly have their place in math and what we teach…their efficiency led them to become the standard algorithms…but there is SO much more amazing stuff throughout the math curriculum than *just* the algorithms!

TeachingWorks director @deborah_ball recently sat down for a conversation about doing math—and teaching—with intellectual humility. Listen to the @JSTOR_Daily podcast here: https://t.co/qHW9mxi7ao https://t.co/qHW9mxi7ao.

Fifth grade teachers! I've made @openmiddle Depth of Knowledge matrices to show how a single math problem can replace an entire worksheet in fifth grade. Download it now here: https://t.co/WQehGvUwec #iteachmath

Looking to challenge your fifth graders and their understanding of fraction equivalence? Check out this @openmiddle problem from @IanKerr_math: https://t.co/ovn5tEHSgz #MTBoS

Just got 100 K - 3 Puzzle Decks in the mail! They're beautiful!

(A joint project of Math for Love and Early Family Math.)

See the card puzzles here: https://t.co/UlKPwRdQfR

They're not physically available yet, but sign up to get info if/when we're able to make them!

@JohnCUrschel Congratulations!! Well-deserved. FTG!

[John Mull @JohnMull]

@angeladuckw @TeresaAmabile @educationweek Yes! But frequently overlooked and hiding in plain sight is how teachers need to use creativity themselves in their everyday work as teachers! Nurturing student creativity is only part of the story.

[John Mull @JohnMull]

Creativity is important to all professions, but especially teaching. Nurturing student creativity is only half the story. Encouraging teachers to also be creative in their own work is essential for dealing with the myriad complexities of teaching. https://t.co/AomvGHvmUI

The fifth hyperfactorial: 5⁵ × 4⁴ × 3³ × 2² × 1¹ = 86400000 milliseconds is exactly 1 day

1 day has 24 hours: 24=4·3·2
1 hour has 60 minutes: 60=5·4·3
1 minute has 60 seconds: 60=5·4·3
1 second has 1000 milliseconds: 1000=5·5·5·4·2

[John Mull @JohnMull]

Great discussion about the value math teachers add IRL that AI still isn’t able to replicate. The art of teaching/learning math is filled with important micromoments that are easily overlooked but extend far beyond modeling proper techniques and accurate mathematical solutions.

[Dan Meyer @ddmeyer]

🌴 I wrote about ChatGPT and the three hurdles it would have to clear before we could call it transformative for teaching.

If you don't have all the facts yet, you shouldn't have a strong opinion yet.

Motivated reasoning is believing what you want to be true. Critical thinking depends on wanting to believe whatever ends up being true.

A key to learning is refusing to let your hopes bias your views.

[Adam Grant @AdamMGrant]

The ultimate test of success is not whether you're proud of what you've achieved. It's whether you're proud of who you've become.

Accomplishments highlight your skills. Relationships reveal your values.

If excellence is what you do, character is what you do for others.

[John Mull @JohnMull]

@Lightning__Jay Congrats!!
