Before I begin, full disclosure, I am VEX Robotics’ full time education manager.
However, Blake and others know my roots are in FIRST programs (FRC103 & 1712, FTC game design, FIRST Senior Mentor, etc). In my 15 years around robotics competition and education, I’ve done a bunch of curriculum/standards/alignment oriented work. My first related project of note was this one: http://www.chiefdelphi.com/media/papers/1898 where I matched education standards to FIRST programs in the states in my area.
With that aside, addressing your question …
There are two “complete” offerings out there - standards matched, completely free and available, teacher and student materials, rubrics, worksheets, the whole deal. You can grab individual lessons, units, or an entire course. However, they use different platforms - the more affordable and powerful VEX IQ and also the classroom battle-tested VEX EDR Platform.

Although these offerings use different platforms, a lot of the materials could be adapted to other platforms, easily. They are already widely used in school settings around the globe. Take a look at some units in each offering and the course syllabi. Also note the VEX IQ Curriculum is geared to elementary and middle school, but this can be scaled up in many cases and/or the more advanced content from the EDR Curriculum can also be adapted to the IQ (or other) platform if desired. I believe Chris Gregory in NJ (FRC 1089) is using IQ in his HS curriculum, for example.
In addition, VEX IQ is very affordable, with a Super Kit retailing for a mere $300. The Classroom bundle is also a VERY affordable deal. http://www.vexrobotics.com/vexiq/products/kits-bundles. VEX EDR is also very competitively priced. (http://vexrobotics.com)
Yes, LEGO Education does have curriculum for ev3 (it only installs electronically alongside the programming software and watch out for the expense/hidden cost, and there are more limited opportunities to scale up to high school age). I think you’ll find the IQ and EDR curricula to be much more affordable (hard to beat free, right?), flexible, and user friendly.
If I sound a little sales-pitchy, it’s only because of my passion for the topic. I think there are still lots of folks on these forums who can vouch for that.
As a fervent supporter of all STEM related robotics education activities, I’m thrilled you have a course in the works and I wish you well in your endeavors. If you ever have any related questions (about VEX Curriculum or about robotics curriculum in general), please feel free to get in touch. Best wishes with this important next step in your community.
