Third-grade students in the Islip School District can add another book to their shelves, as members of the Islip Elks Club Lodge 2533 continued their seven-year tradition of delivering “A Student’s Dictionary” to each third-grader. During the Elks’ tour of third-grade classes at Commack Road and Maud S. Sherwood elementary schools, Bruce Trezise, youth chairman for the club, noted that over the years the project has delivered close to 4,000 dictionaries to the students of Islip.
