 Schools remained open, with replacement teachers and administrative staff showing movies, filling in for the striking teachers, but school attendance was estimated to have dropped to less than half during the strike.Students at Venice High School created a buzz on Twitter when they danced in support of their striking teachers, issuing a Public Ed Dance Challenge to other students to learn their dance steps and join them on the picket line.Meanwhile, thousands of teachers clad in red union t-shirts, waving signs that read, "Save our Schools," continued to attend rallies with community supporters around the city, including at City Hall and LAUSD headquarters.
