Pin It Now! I'm very honored to be part of a fundraiser organized by The Center Based Classroom for those affected by the Boston Marathon bombing. Michaela has put together 2 bundles of donated TpT products (K-2 and 3-6) worth more than $150 each. You can purchase these bundles for a donation of $20 each. Your entire donation will go to the One Fund to help the victims of the Boston Marathon bombing. Visit The Center Based Classroom blog to view the bundles and donate.
