CHICAGO (AP) — Parents and students are figuring out their options on the first day of a Chicago teachers' strike.

The district is keeping some schools open, and they're serving breakfast and lunch, but there's no instruction and it's only for a half-day. District officials plan to feed and monitor students at 144 schools throughout the city during the strike.

At one high school, a handful of students trickled in as about two dozen teachers picketed outside. One 17-year-old said she only came to school because she didn't have anywhere else to go.
