Birk said she got her information from the parent of another fifth grade student at Maugham. The student was in a different class, but students "still had to walk down the hall and see it," the Englewood woman said in an interview.
The parent said the work was part of a teacher-approved "character development" project for the entire class, according to Birk.
"It was up for at least two weeks," she said.
Birk's Facebook post drew angry responses from the community.
"How is this possible in (one) of the most Israeli towns in the country?" Jodi Karsch Cohen commented. "I am disgusted."
