TLD 2013: Common Ground will consist of a suite of short, carefully prepared talks, demonstrations, and performances on a varying range of subjects to foster learning, inspiration, and wonder - and to provoke conversations that matter. Be ready for some surprising talks prompting you to find common ground among seemingly unrelated ideas, which just so happens to be the very power of primary sources! Focus will also be given to demonstrating the seamless integration of the new Common Core State Standards with primary sources and technology.
