For 15 years, Oprah's Angel Network has been helping students in the United States and many other countries realize their educational dreams.

"From a few pennies in a bucket to an $80 million force, your money has lifted up thousands around the world," Oprah says.

With the Angel Network coming to a close, it's now time for the last giveaway in the organization's history.

Oprah turns to the founders, principals and teachers of Aspire, LEARN, YES Prep, Mastery, Science and Denver to share a surprise announcement.

"I know that thousands of kids are waiting to get into your schools, and I value nothing more in the world than education," she says. "So the Angel Network is giving each of your charter school networks $1 million!"

Watch the reactions of these inspirational educators.
