“RIIIING, RIIIIING, RIIIIIIIING!” School bells are ringing and classrooms are filling up with students eager to master reading, long division, biology, and history.To make sure students have the supplies necessary to succeed this school year, DonorsChoose.org is backpacking across the USA! Along the way, we’re stopping in classrooms all 50 states (and Washington, D.C.) to "fill our backpack" with basic supplies.Teachers have requested backpacks, pencils, folders,calculators, and so much more for their students. Check back each week to see what state we’re in and what supplies have made it into our backpack!This is the year to help children in your state and across the nation start school on the right foot. All aboard!
