I am teaching VEX robotics as a class and I am looking to expand
the games I teach within my classroom.
Does anyone out there know what I can buy those “Blue” cubes that were played in past VEX games? Thanks for your time and for being a great resource.

I think this game might have been played in 09. Anyone??
Red and blue 3" foam cubes were used in Elevation, which was the 2008-2009 game. I used to have a bunch of them. 
yeah they were 3" red and blue foam cubes from the 2009 game Elevation. I understand wanting to add more games to your selection, but I would suggest adding another year’s game to your arsenal. The cubes were the easiest game objects to damage in recent years, and if this is for a classroom setting, I’m guessing you would want the objects to last for a while.
The 2008 game Bridge Battle used tennis balls for game objects and the other field objects were very easy to build out of plywood and PVC.
The 2010 game Clean Sweep used small foam round balls and foam footballs, however this foam was definitely more durable then the Elevation cubes.
The 2011 game Round Up and 2012 Gateway both used hard plastic game objects for their respective fields, and they were extremely durable.
Sack Attack from last year was pretty good unless you ripped the sacks.
I would start with 2011 and 2012 if you would like the supplies to last a long time. If you are okay with DIY a bit more, 2008 would be great IMO because it was quite some time ago now and it will bring out more unique designs. Also tennis balls are very easy to get your hands on.
Here’s a link to all the past games and their info.

Hope this was helpful.

Thanks for the info and advice. My class are currently playing swept away, and round up, and for next year probably sack attack.
Just thought I would add something with the cubes for some intro robotics classes. I appreciate your time and help!
ask around teams in your area to donate this years objects after worlds
Oh, question on this note.
This is the first year we’ve bought a full field. We have 10 LB, 25 BB, and all the hardware to dispose of at the end of this year. This is just a club, not a class. So what does everyone else do with them?
I am not sure how it happened but I saw a gateway object rolling around my Friday school last week 
We usually keep some of the objects around for a year or two before finally throwing them away. (don’t ask my why)
I think my mother used the sac-attack sacs for a carnival game.
Last year our coach handed out the sacks to people.
All our objects from the past 4+ years are sitting in a storage closet at our school.
If you’re interested in cheaper alternatives to past VRC games in New Zealand we have something called KiwiChallenge. It’s designed for students new to Vex as an introduction to the main competition. All the game elements are easy to find at local stores (in NZ at least) and cheap too. The games are also quite a bit simpler than the VRC games. If you want more information check it out here.
