Summer in the Square

That’s Union Square Park in Manhattan, which has more than playgrounds and lush grass to lure children each summer. This free Thursday series from the Union Square Partnership offers family activities and entertainment through Aug. 13. It includes Yoga Story Time, from the yoga studio Karma Kids; a concert or show (this opening week it’s Kidville’s “Rockin’ Railroad” program, for children 5 and under); story time with the Strand Bookstore; and exercise with the 14th Street Y and Pop Fit Kids. And a Children’s Activity Pavilion, with crafts, books and games, is open all day.
