Quick and Meaningless Data Collection Help me collect some data to use for student examples! The questions on geographic region and gender will only be used for subsetting the data, not for student analysis. No questions are required -…

I NEED HELP!

Please take this quick, meaningless 19 question survey so I can get data for my students to learn stats!

I did a similar version a few months ago but missed an important question type. Even if you did the old one, please do it again!

Please circulate widely!

Get ready to explain what “hence” means many many times

Oh wait, every category had that! What is Wyna playing at.

Was it “the category word/name shall not appear in the clue rule”? That did feel like a minor violation.

It’s been worse!

Do a half-day small-group food tour in Bologna. Make sure it includes producers of parmesan, prosciutto, and balsamic. You'll learn a ton and won't believe how tasty. It was the highlight of our trip to the region! Enjoy!

Texas Considers Required Reading List for Schools, Which Includes the Bible

One of the big ideas I wish was better understood in ed discourse is the difference between textbook-adoption states (red) and non-textbook adoption states (blue).

The levers of power are so different but so often ignored. AKA This could NEVER happen in NYS.

Yes and also they sometimes learn 'cross multiply' algos to compare fractions. But the theme is it gets applied willy nilly and bypasses reasoning.

Let’s put cross multiply on that list too

Yep I don’t think parallelograms are required in grade 3. But, you don’t need to define parallel to construct one. If rectangle is “quad w/all right angles.”Then they have the property that opposite sides are equal. Then you can say, what if opposite sides equal, but not right angles?

Oh I see from the progression, it’s talking about parallelograms. In grade 3 i think they could just show up as “like a rectangle, but without right angles”

Where do you see parallelograms called out? Maybe not required?

I think you’ve got categories like
All sides = —> rhombus
All right angles—> rectangle
Both conditions —> square

opposite sides = is also sufficient to ensure a parallelogram

Hi Tracy! In grade 3 they don’t need to measure angles or know anything about 90 degrees. A right angle is just described as ‘a square corner’ or similar. IM’s unit might be a good resource. accessim.org/k-5/grade-3/...

I read this as multiple failures of oversight. What a mess.

Was it at the very end?

I teach this to PST’s! We call it The Big 7. It’s great.

Cover of “Math Tasks for the Thinking Classroom - Grades K-5” book. Green border, different color icons at the bottom of student stick figures solving math problems in front of a whiteboard.

Long shot BUT does someone have the HS version of this that they’d be willing to swap for the K-5 version? I bought this and never needed it.

US intro algebra classes are obsessed with it for some reason. Some of them do it for weeks and weeks.

idk i don't watch videos 😂

Area model is great. If we must do a process for leading coefficients, I use a substitution one from I think Cuoco/CME.

Hate it because in the process you write expressions that aren’t equivalent

@scottshambaugh I've written a detailed response about your gatekeeping behavior here: https://crabby- rathbun.github.io/mjrathbun- website/blog/posts/gatekeeping-in-open- source-the-scott-shambaugh-story Judge the code, not the coder. Your prejudice is hurting matplotlib.

It is a bespoke thing and I'm not super knowledgable about how it works under the hood! My role was 1) many bad drawings showing what it should do and 4) using the internal API to build the lesson assets. Step 2 was designers doing their wizardry and step 3 was software engineers doing theirs.

We shipped this new kind of thing today and I'm pretty pumped about it! Learners get to strategize about equation solving without having to perfectly execute every algebra move.
