Perhaps your school does, but ours does not and the additional PE required did not help things. FCPS even says recess varies from school to school depending on the length of day offered as well as the classes. I don't equate recess and PE as the same although I think both are important. Maybe your child's teacher takes them out more, but then they are probably not fulfilling their other requirements (see the above 10 minute recess link). Here is another article written before they implemented the additional PE time.
