S got solutions of 6 (true) and 27 (extraneous) as solns to radical eqn.

S: Why is that? Why 27?
Me: Ooh! Let's pull out @Desmos and see if we can figure it out! (afterward, algebraically)

LOVE it when S curiousity shows up even on a review day.

@TJTerryJo @park_star Me too. What is up with that?

[Heidi Neufeld @HeidiLNeufeld]

@evandcole @SaskTel I got three today from random countries!

[Heidi Neufeld @HeidiLNeufeld]

Ya’ll.

Just submitted my final assessment for the last course of my last bachelors degree.

We’ll see if I can last a year before looking at masters courses.

Major mathematical wanderings in PC20 today
Started with Geo sequences
Got into fibbonaci and phi
Deductive reasoning, proofs

Now one of my S is using her break to see if 47 is evidence for or against the collatz conjecture

Having WAY too much fun RN giving feedback to Ss on:

If I paint a room by myself, it takes 3 h.
If my brother paints it, it takes 4 h.
How long if we paint it together?

One S has (unknowingly?) connected geo. series and rational eqns.

PC20 win!

One of my fav things about @CityParkSchool:

Kids of all ages appear in my room asking, "Can I ask you about something about math?"

SUCH FUN to think alongside people from a variety of places.

PC20 today: All S solved a system algebraically. Half got one Soln set, half another. They switch work and identify differences in strategy. Good conversations ensue.

Later, S confesses "I verified. I couldn't take it anymore."

I'll take that win!

S quote from today in pic.

This is why I love starting quadratic fns by getting S to sketch a few graphs using TOVs for fns in vertex form.

So many great observations just get said aloud with no prompting.

@MathCurmudgeon @CityParkSchool @StoonPubSchools Oooh!! Love the addition of the inverse. I’ll give that to them tomorrow!

[Heidi Neufeld @HeidiLNeufeld]

A prompt I’m proud of: (PC30)

Sketch the graph of a fn that will not change after the transformation y=f(-x) is applied. Can this also be done for y=-f(x)? Explain why or why not.

Resulted in great S reasoning and articulation.

You know you love math when you recognize the unnamed voice of @stevenstrogatz in a @Spotify ad.

PC20 Sequences & series
I ask Ss (in their at home work) to create a sequence that is neither arith. nor geo. and explain their rule.

So far exponential, quadratic, factorial, periodic patterns.
I can't resist finding multiple representations!

Logarithmic growth sounds like this:

"What? We doubled the height, and the time it took for the ball to fall barely changed!"

Today my Ss rocked their way through 2 regression labs, courtesy of @NatBanting and Steve Vincent of @TommyDTigers.

@StoonPubSchools @CityParkSchool

[Heidi Neufeld @HeidiLNeufeld]

Same.

[Nat Banting @NatBanting]

I'm trying to tell myself that this is the best I can teach under these circumstances.

Having a hard time being convincing.

Decided to embrace PPE in my costume this year.

[Heidi Neufeld @HeidiLNeufeld]

Ready or not, here comes quint 2!!

Pumped to get a new group thinking in this space.

@StoonPubSchools @CityParkSchool

[Heidi Neufeld @HeidiLNeufeld]

Finished off the quint in FPC10 by measuring this inaccessible height in the @CityParkSchool commons.

What did we learn?
Make sure your calculator is in DEG.

[Heidi Neufeld @HeidiLNeufeld]

Dreams do come true.

That right there is an accordion portable whiteboard for my room, thanks to @scottstp.

At the start of class today:
Asked Ss to predict opp side, given hyp = 70, angle = 50, as compared with angle = 30.
One S whips out his calculator and declares, "It's gonna be 64% of 70."

Blew me away. They GOT this.

[Heidi Neufeld @HeidiLNeufeld]

VP: How was today?
Me: Awesome, I got to intro trig
VP: I don't see how thats possible

Had Ss draw triangles and calculate ratios BEFORE giving them formulas and labels. Noticing patterns, making predictions, being curious is awesome.
