The school day at GMS runs from 8:30 a.m. to 3:15 p.m., every weekday except Friday, when instruction closes at noon. Our after-care program begins at the close of the school day and ends at 6:00 p.m. Parents must register their child for after-care if they plan to use it on a regular basis, but use on an occasional basis is also possible so long as there is room. After-care fees are not included in tuition and are paid monthly for the number of hours used. Currently, the fee is $6.00 per hour per child.

GMS students (and teachers) bring their lunches to school, except on the one “hot lunch” day each week. On that day, students can buy slices of hot pizza and their choice of fruit, crisp veggies, cookies, and juices. Another "staple" of the GMS school day is recess, where students can burn off energy at the playground or by playing outdoor games together.
