Geogebra documentation

November 29, 2017


SetCoords Command   SetCoords SetCoords( <Object>, <x>, <y> ) Changes cartesian coordinates of free objects. This command uses values of the coordinates, not their definitions, therefore the object stays free. Note: This command now works for Sliders, Buttons, Checkboxes, Input Boxes, Images. If “Absolute Screen Position” is selected then x, y are in screen pixels. My template has stuff like this SetCoords[I1_1,x(%1),y(%1)]”,”SetCoords[I2_1,x(%2),y(%2)]”,”SetCoords[I3_1,x(%3),y(%3)] […]

“This.” That is a link to a Geogebra animation of a machine pumping up a balloon full of air. I had, on my drive, dismissed those kinds of animations — precisely the “filling up” animation. I am NOT going there.  Yet. I’ve been disillusioned often enough by geogebra not to interrupt even after I see […]

Another webinar!

November 20, 2017


It’s a little harder for me to talk about this webinar, w/ Jo Boaler, because a:  I was there, and b: I’ve been following Boaler’s work for a few years now, so this wasn’t such new territory.   I remember that first “Mindset” course for teachers 🙂   Number talks and dot cards, yes! The gist is […]

Inclusion, eh?

November 15, 2017


Interesting American Institutes for Research article in EdWeek about inclusion and the idea that it simply decreases actual instructional time — not because the sped students are “slower” but because of behavior issues. It basically says teachers don’t have good training (‘lack knowledge of positive classroom management techniques,” etc.)… … but otherwise … yea, I’ve […]

Wish I knew…

Let’s talk about this on general terms… So a student comes in and … they’re struggling.   There’s a lot they seem to know… strengths abound… but wham!  they keep crashing and burning… … how much is the math model? … how much is oh, symbol overload (e.g., students who will have no trouble w/ the […]

more geogebra annoyances

November 6, 2017


So I make a point like it says to do in the “how to make text” because I want to make text that is attached to a point so it moves when I drag it. It says “Then, a dialog appears where you may enter your text, which can be static, dynamic, or mixed.” Now, […]

Geogebra.   “Lists” are a lot like arrays, tho’ the first element is list(1) not zero; zero will get “undefined. No, I still have no idea how to actually SET THE STUPID X AXIS TO THE SIZE I WANT.   I mean, I know how to set it but it changes if I so much as move […]

The beat goes on

Further progress in The Project.   So — going to up the threshold for what I post here.   The “gee I had a good day” type stuff will go to “”  … and I’ll post here as if I had 73 or more followers because there’s ever so bit of chance that could happen. Growth mindset. […]

wow :)

I *think* I did a mess of admin stuff reasonably well, checked the to do list … and *then* dove into Geogebra for a few minutes exploring instead of  random distractions (like blogging?) So there’s a function for dragging and dropping.   This has been my dream for years 🙂 Now I have no idea what […]

Good busy

November 2, 2017


… and yes, now is about the time in the semester when we start reaping the benefits of The Slow Way.   All those folks who got the long explanation and discussion of rounding and place value… gee, we’re multiplying by decimals… why are we moving the decimal?  Understanding is happening *faster* and we’re getting back […]
