Mayor Bill de Blasio on Thursday announced an expansion to the 3-K for all program to other boroughs.

The program offers free, full-day schooling for 3-year-olds and is currently only available in the south Bronx and Brownsville. But starting with the 2018-2019 school year, the mayor says it will include District 4 in East Harlem and District 27, which covers parts of Queens.

He says the program will help New Yorkers generations down the line.

"Those kids with that strong foundation will do better in school over all the years ahead," de Blasio said. "They will get a better education. They will be better prepared for their future. They will be better preparepd to enter the workforce because we reached them at the beginning and we reached them the right way."

In the coming years, there are plans to expand to more school districts in the Bronx, Staten Island and Brooklyn.
