We love learning, and teachers love teaching, so it should come as no surprise that ThinkGeek would donate $1,000 towards a DonorsChoose Back to School challenge for teachers.

Starting today, DonorsChoose is asking their community to share their favorite elementary school memory by noon EST on Tuesday, September 18. Ten winners will each receive a $100 ThinkGeek gift certificate and will be emailed their prize at the conclusion of the contest.
