Some parents in Corona say they are fed up with their children being forced to attend classes in trailers.
Dozens of parents gathered in front of PS 143 on Tuesday in support of a plan to build an addition to the school.
State Senator Jose Peralta is proposing building the addition next to the existing school on land owned by the City Parks Department.
More than 150 first graders at PS 143 currently attend class in trailers.
Parents say the school building is meant to serve 900 students, but enrollment now tops 1,800 - and they say class sizes are too large.
“If we have smaller groups, the education will be better, children will improve academically and that's what we need, you know - we don't want to get left behind," said one parent.
"These kids are learning in these trailers that don't have air conditioning, that's a problem," said Queens Senator Jose Peralta.
The Parks Department says it is working with the School Construction Authority to determine the feasibility of the proposal and the impact it would have on existing park space.
