Before Halifax Elementary School students head back to the classroom this week, parents can check the school’s website for supply lists posted for each grade level. Kindergartners, for example, should come equipped with backpack, lunch box, a 10-pack of washable markers, 10-pack of colored pencils, 10 glue sticks, 10 sharpened pencils, and a one-subject notebook. For other lists, check www.halifax.mec.edu. Opening day for first through sixth grades is Wednesday. Kindergartners have an open house from 9 to 10 a.m. that day and officially start school Thursday.
