"She has slammed her fist in these cars and told them that they need to stop for these children. She has put her life on the line for us, so now we're putting our dollars out for her," said parent Gabrielle Aguilar.
Deb Clark, a 50-year-old mother of four, is being forced to move from the apartment where she has lived rent-free for 12 years, the Chicago Tribune reported last month.
With a potluck and fundraiser, the parents aimed to raise enough for the first and last month's rent in a new apartment and give the woman a bit of a financial cushion.
The kids were as supportive of her as their parents, loading plates up with food and heaping praise upon their favorite crossing guard.
"It was just such a warm feeling when I started the day," said one student.
One of the parents who has been helping in the apartment search said Clark applied for the first place she's found that fits her needs and her price range just hours before Friday's event.
"I thank, I thank everybody. Thank everybody from my heart," said Clark.
