Superintendent Richard Carranza spoke to students of Bret Harte Elementary School in the Bayview district who received kits Monday morning.
The distribution was made possible through a district partnership with the nonprofit K to College that will reach 12,500 students at 30 schools through the end of October, K to College co-founder and Executive Director Benito Delgado-Olson said.
At least 80 percent of students at the participating schools already receive a free lunch, Delgado-Olson said.
Low-income families juggle their finances between clothing, food, transportation or other needs to make ends meet, and the kits provide one less stress for them, SFUSD spokeswoman Gentle Blythe said.
The organization also plans to distribute dental kits one week before Halloween, when many children eat sweets, Delgado-Olson said.
Each student will receive a kit worth $65, he said, and the supplies are appropriate to their grade.
The nonprofit will continue to serve the district as schools may identify more homeless students throughout the school year, Delgado-Olson said.
