@davidwees.bsky.social is in Hong Kong teaching!!! Don't know if he can help

Cool factors today Mike!

Fence posts vs. fence panels!
[the numbers in the sequence are like fence posts, every two numbers are separated by a "panel" which is the jump... Ss have a hard time at first seeing that 3 numbers separated by 2 jumps, n numbers separated by n-1 jumps]

Thank you for witnessing this and telling about it here.

Gotta be happy about the small things, because ... {waves at the world around me} 🤷‍♀️
And very happy to have you as my friend.

I switch between a couple of start words. The one I chose today helped me get it in TWO! (Rarely happens! So glad I didn't used my other start word today.)

73 – 37
Imagine a number line
37 to 40 = 3
40 to 70 = 30
70 to 73 = 3
Add up those jumps = 36
Or
Subtract by place value with negative numbers permitted
73 – 37
70 – 30 = 40
3 – 7 = -4
40 + -4 = 36

I like @emilymbender.bsky.social 's
"synthetic text extrusion machines" from The AI Con ...
I also use: "plagiarism engine" and "text regurgitation tool"

How about reframing this as being empowered to ask for what you need (self advocacy)??

Wonderful & amazing!!

David, I had to craft this alt text carefully on a different "how many" question...

Ok, at least it's not fatal 😜🤣

This image shows my thinking... encourage your students to try out various strategies (try & revise).
Where is an easy starting point for you?

Spoiler...

Body Benchmarks! Body Benchmarks: Analyze the Data and See How You Measure Up! I first used this activity in an Algebra I class when I wanted students to have a hands-on experience gathering data and modeling it wi…

Yes! & the room at ATMNE was sloped up w/stadium seating & sloped ceiling w/different pitch than the floor!!
(Kim planned for rectangular prism room, so was harder than expected 😉)

This is my favorite all-ages measurement activity from family math night :

You ok?

My favorite measuring tools include my feet/ footsteps/ pace length and also "wingspan".
Jenna, were you in the "Math For Wigglers /Dreamers" session at ATMNE w/Kim Machnik? We measured the volume of the room...

I made date blocks during the pandemic... based on something you posted!

What? No 5's?? That's where I usually start 🤷‍♀️😉
Must look for the 7s instead...

Now and re-post in morning also.

See if you can reframe the learning task for the experienced student: what does this add to my prior understanding?

...Despite their reasons for retaking, remind them their job in this class ISN'T to teach classmates. That is stealing other Ss' opportunity to think, learn it deeply themselves.

Ok, I feel your pain...
One idea (thanks to @sneffleupagus.bsky.social ) is "Vuja De"... seeing the same thing through different eyes (vs. Deja Vu).

Maybe encourage student to look at calc w/fresh eyes, learn it more deeply themselves, try to make connections to past knowledge.

Spencer, is this HS or college? And if college, is it intro calc or more advanced?
I'm thinking that you might have a student who took AP in HS but is repeating (for whatever reason) so they "already know it".

8 • 27
2^3 • 3^3
(2•3)^3
6^3 which I happen to know = 216
Or
8 • 27 can decompose & distribute 2 different ways:
8(20 + 7)
8•20 + 8•7
160 + 56 = 216
Or
8(30 – 3)
8•30 – 8•3
240 – 24 = 216

Find derivative of f-inverse-of-a, when we know f.
For f-inverse, a is an X value.
For f, a is a Y value.
Find the X value such that f(X) = a
Find f'(x) at that X value, then find reciprocal of that.
{I never present the formula without all that explanation... too confusing}

Here's how I explain the derivative of the inverse situation:
Since the inverse swaps X and Y, the derivative (slope) is the reciprocal of the original function derivative.
And point of tangency has also swapped X and Y. So need to find the other coordinate from original function...

Thanks David!
