Roughly 51,000 Big Apple kids switched from remote to blended learning during a Department of Education opt-in period this month, according to the agency.
That brings the total number of city students participating in classroom activity to 365,000, according to the DOE.
There are roughly 960,000 kids in the system and the vast majority will remain on a remote-only basis for the rest of the school year.
All of the new blended learning kids will be absorbed into their schools on April 26.
Mayor de Blasio said at his daily briefing Monday that elementary schools will be allowed to lower social distancing restrictions from 6 feet to 3 feet while higher grades will stick with the current format.
Citing shifting CDC guidance and an easing of COVID-19 indicators, critics have been pushing for a wider reopening of city schools in recent months.
City officials also said Monday that 28 percent of all teachers currently have medical exemptions that allow them to work from home for the remainder of the year.
Schools Chancellor Meisha Ross-Porter said Monday that the DOE will likely “reset” coronavirus accommodations before the start of the next academic year, meaning teachers won’t automatically have those exemptions.
