OKLAHOMA CITY - Monday is the first day of the school year for about 46,000 students in Oklahoma City Public Schools, the state's largest school district. 

Oklahoma City Public Schools is the first district in central Oklahoma to return to class.

The school district is asking parents and students to share their first day of school stories and photos on Twitter by using the hashtag #OKCPSDay1 or to email the district at applaud@okcps.org.  

New this year are the start times for Classen School of Advanced Studies and six elementary schools. They will start at 9:10 a.m. and finish at 4 p.m. The district said the time change will save them $700,000. 

Area drivers are also being urged to stay alert for children walking or biking to school.

AAA spokesman Chuck Mai said the afternoon hours are particularly dangerous for walking children, with nearly one-third of child pedestrian fatalities happening between 3 to 7 p.m. over the past decade nationally.

Mai said drivers should obey school zone speed limits, monitor blind spots while backing up and eliminate potential distractions, such as using cellphones, among other measures.
