About 1.5 million kids and teens are homeless in the U.S. One and a half million! And do you want to know the one item that they often request? A pair of blue jeans.  

DoSomething.org is launching its annual Teens for Jeans campaign to help. Here's how it works:

Register on the site to get all of the details, then start planning your jean drive. Official collection dates run from Jan. 20 through Feb. 16. Every student who participates will be eligible to win a $4,000 scholarship, and the school that collects the most jeans will win a $10,000 grant, Aéropostale T-shirts, and a party.

This is the sixth year that DoSomething.org is running its Teens for Jeans campaign. During the first event, 1,000 young people participated. Now, Teens for Jeans is in half of all high schools in America. Over the past five years, Teens for Jeans has provided almost 3.3 million pairs of jeans to more than 1,000 shelters in the United States and Canada — enough to clothe almost 50 percent of children and teens experiencing homelessness.

This year's goal is to collect 1 million pairs of jeans.
