I'e been using GeoGebra with my math classes (online, 7th-12th grade) for several years.

Here's how I use it:

With students:

- When students need to generate a graph (usually of a function) as part of an assignment, I recommend that they create the graph in GeoGebra and take a screenshot (several different programs/website work for this, so I usually give them a choice of GeoGebra or Desmos)
- When teaching constructions in Geometry, I spend a week on how to use GeoGebra to create constructions after they've already learned how to use compass and straightedge to do so. Some of them choose to use it the rest of the year instead of graphing by hand for various tasks or when generating figures as part of an assignment.
- You can also do some stats graphing in it, so they'll use it for generating graphs in that unit as well.

As a teacher:

- When I need to generate a graph as part of an assignment or quiz, I will use GeoGebra and take a screenshot
- When I need to generate a 2-d geometric figure as part of an assignment or quiz, I will use GeoGebra and take a screenshot
- When grading something where each student will be giving me a different problem (and thus, it's hard to create a static key) I will use GeoGebra to quickly check student work:
- For example, I recently gave an assignment where students needed to given an example of a quadratic with complex roots as part of their assignment. Rather than taking the discriminant of each student-generated quadratic to double-check that it had complex roots, I copied and pasted their functions into Geogebra to see if they had x-intercepts. That was much faster for me while grading.)
- I also find it useful for finance-based assignments where they will all be using the compound interest formula but with different principals, interest rates, and compounding periods based on their individual research, because then I can just edit the function I had from the previous student. (Questions like "for your principal and interest rate, how much will your saving account grow in 30 years? When will it have at least $10000 in it? can be easily modeled as a system of equations with horizontal and vertical lines for the values they are supposed to be finding, the intersections selected as a point in Geogebra so I see the values in the left-hand column, and then I just edit the function with the compound interest formula in it for each student's values and see the new points of intersection to quickly double-check their calculations even though I can't make a static key.)

I just had a teacher ask about this last week. After poking around a bit, it looks like we can add it from the App Center but the only integration that I saw was teachers could add it to a module via External Tool.

I can't share any more than that as I am not a math teacher, but they seemed to be interested in getting it working!

It does seem like it might be more useful if it could be added to the Course Navigation or as a link on a page so students could access whenever they wanted to.

Adding it to a modules seems like you'd have to be fairly thoughtful in your placement...and would have to add it in multiple places each time you want them to use it?

I think it might make more sense to maybe use the Redirect Tool and point it to the GeoGebra Graphing Calculator website. Graphing Calculator - GeoGebra

I added the Geogebra graphing LTI and whilst I would like to have the option of it on a page, it works well on a module.

The only issue I have is that size of it. On our Canvas page there is a HUGE white space not being used at least 1/3 of the available page is empty. Is this just me? Anyone know how to improve on this?

Funny how serendipity works. Random search led me to this and I just saw an email today related to Geogebra. Now I am doubly interested. Is anyone using this with or without Canvas that can give me a quick synopsis of how they use it?
