Imagine students learning their ABCs while dancing, or memorizing multiplication tables while doing jumping jacks.

Some schools are using both methods of instruction, and Michelle Obama would like to see more of them use creative ways to help students get the recommended hour of daily exercise.

In Chicago on Thursday, the first lady was announcing a new partnership to help schools do just that. It starts with a new website, letsmoveschools.org, where school officials can sign up to get started.

The effort is the newest part of Mrs. Obama's 3-year-old campaign against childhood obesity, known as "Let's Move."

Mrs. Obama is on the final day of a two-day tour to promote "Let's Move," with appearances Thursday in Chicago and Springfield, Mo.
