Children are already heading back to school in some of the two dozen school districts in south Louisiana forced to close after massive flooding. But their teachers and their schools still need help.

Dozens of teachers on the education crowdfunding site DonorsChoose.org are asking for donations to rebuild their classrooms.

One Baton Rouge elementary school teacher wants to buy classroom furniture and math activity supplies lost to flooding. Another Baton Rouge teacher is seeking donations to buy books and bookshelves for her class. In Denham Springs, a middle school teacher says she needs bookshelves, a rocking chair and Harry Potter and Hunger Games book sets for her students.

"So many of them have lost so much and don't know when or if they'll be able to return to the place they once called home," the teacher from Baton Rouge's Broadmoor Middle School wrote in her request. "Being able to recreate our classroom into a special place that's filled with all the tools needed to promote independent and grouped learning will mean so much to my students."

Several other groups, including the Louisiana School Boards Association, Associated Professional Educators of Louisiana and the NEA Foundation, are also collecting funds to help schools affected by flooding.
