Worried about the health of students and teachers in stifling classrooms, Minneapolis school officials canceled classes Thursday and Friday in its 27 buildings without air conditioning.
Wednesday's decision came after three days of shuffling kids into cooler rooms or outside, ferrying water, Popsicles and ice into hot classrooms and feuding over where the limited number of fans should blow.
Teachers were also tasked with watching the kids for sign of heat stroke, adding to the pressures of the first week of school.
The district said the successive days of record or near-record heat were taking a toll on students and teachers.
"We could sustain this for a couple of days … but staff members as well as students have been sweating all day long. At some point, we don't want folks to start becoming ill," district spokesman Stan Alleyne said.
Asked if the decision was based on pressure from parents, teachers and kids, Alleyne said it was more about the conditions.
"Even with the extra water and extra fans, they're in hot buildings," he said.
Classes at those sites will resume on Tuesday, after the Labor Day holiday. Students will not need to make up the canceled days, and students are expected to report to the other schools as usual.
