This one was fun! Lots of alternate "solutions" if factors can repeat, but I had to write out the prime factors in order to solve it with unique factors...

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

We had a lovely session, talking math talks and same & different.
Slides at bit.ly/ATMNE-math-routines for anyone playing along from home or at a different wonderful #ATMNE25 session.

I derive values from half-square & half-equilateral triangle (like others)
Also, helps to highlight how the 30° & 60° are same triangle oriented two ways.
Finally, nice trick to see that 1st quadrant values have pattern: sqrt(0)/2 → sqrt(1)/2 → sqrt(2)/2 → sqrt(3)/2 → sqrt (4)/2

Hello #iTeachMath friends! If you're attending ATMNE New England conference this week, come to hear me & @sneffleupagus.bsky.social present on "Building Community thru K-12 Math Routines"
Shelby's a wee bit taller than me so I made her sit for this photo.

Hi Shaun, I want to dive into multiplication of factors, hard for students.
(x - (1 - 2i))(x - (1 + 2i))
I've seen 3 ways: what do you think?
Method 1 Repeated distribution (shown here box method)
Method 2 Notice Difference of 2 squares to help
Method 3 Set x = 1 - 2i, square both sides

These are excellent & love the name too (like @mrlevmaths.bsky.social) !
I do "Same & Different" as a prompt, here are some integrals from my calculus-focused post -- which has Catriona's examples included at the end of the post.

I used 3 ideas:
-Right triangle with hypotenuse = 10
-Geometric mean** of the 2 parts of diameter
-the question asks for area, not the dimensions separately
**thanks to @howiehua.bsky.social I've had the different means on my mind.
In marked diagram --> y is geometric mean of w and x.
