CHICAGO (AP) — The Latest on a strike by Chicago teachers (all times local):
The nation's third-largest school district is canceling classes Tuesday, marking the ninth day of a strike by Chicago teachers.
Chicago Public Schools officials announced the decision on Monday afternoon.

Both sides signaled Monday that they remain at odds over demands for smaller classes and more staff.
More than 25,000 teachers walked out of schools starting on Oct. 17. The walkout has surpassed the length of a 2012 teachers' strike.
A teachers' strike has cancelled classes for an eighth day in Chicago, hours after the school district announced a tentative agreement with a separate union representing thousands of school support staff.

A union spokesman hasn't replied to a message Monday asking when members will vote on the offer.
