Calaveras Community Foundation Strikes Again

One year after generously awarding almost $10,000 via a competitive grant, the Calaveras Community Foundation has again approved our second grant application for approximately the same amount.


​We plan to upgrade our technology used in the ROV development by students, acquire additional EV3 kits as Cybullfrogs enrollment increases, and purchase Arduino kits. This growth in student activity in technology will be augmented by robotic and programming done in CFLC, Avery, and Mark Twain schools, as well as the pending addition of programming classes at Bret Harte. 

"What's Going On?"

Having successfully scheduled numerous Lego-oriented events during the 2014-19 school years, we continue to schedule two-to-three LEGO Events a year, typically, Tug-of-War, SumoBot, and the Exhibition.

Updated rules, descriptions, and resource links will be made available within this page's left column.


Is there an entry fee to participate? No.

Are events open to homeschoolers? Absolutely.

Must participants belong to a LEGO club or class? No.

Can I contact Mr. Randall if I have questions? Certainly.

Can I use either an NXT, EV3, or FATCAT EVB kit? Yes.
