Books have been piling up under the library tree for the last month, and I promise I haven't been hoarding them to cram for the Battle of Brilliance. As it gets colder/icier/snowier, the potential for a digital learning day (what used to be known as snow days) increases... but what to do if the power goes out? No internet? Scant few minutes of battery life? Print books (and a candle) mean you can still enrich your brain.
