MINNEAPOLIS -- Hiawatha Community school is one of 18 schools in Minneapolis that does not have air conditioning.
In Tani Langree's first grade class, water bottles were a back-to-school must-have.
"When we transition from one activity to the next, I ask them to get a drink from their water bottle," Langree said.
For 24 students, seven fans were going constantly. When the heat got too much, students stocked up on ice cubes.
Despite the steps taken, some parents were concerned about the excessive heat.
Allison Herrera's daughter started first grade even though she didn't agree with the district's decision to have school on a dangerously hot day.
"I don't think it would have been unreasonable to delay the start of school by one day," said Herrera.
"I just told her to just take breaks and drink a lot of water," said Herrera.
Minneapolis Public Schools will operate on a regular schedule on Tuesday, but parents have the option to keep their children home if they feel necessary, the district said.
Absences and late arrivals related to the weather conditions will be excused as long as parents follow their school's procedure for excused absences.
After-school activities and athletics, indoor and outdoor, will be canceled, officials said.
For those trying to beat the heat, check out one the cooling centers which are available in Minneapolis and Hennepin County.
