Hingham High School’s PTO will host a fund-raiser from Monday to Friday this week, with 20 percent of sales at Hingham Fruit Center going to the PTO. Participants need to print out coupons to ensure that the funds go to the high school. According to Hingham High principal Paula Girouard-McCann, the money will support the PTO’s yearly activities, which include small grants for teachers, event sponsorships, and two senior scholarships. Girouard-McCann said the PTO is “a great resource, and its other events include a ski and sports sale, the sale of agenda books, and school pictures. For coupons, e-mail PTO president Aylene Calnan at calnanesq@comcast.net.
