Memorial Day, observed on the last Monday of May, is a national holiday in the United States to honor and remember those who died serving their country in the military. Many Americans visit cemeteries to remember their loved ones, lay flowers, and take part in parades.

Because it falls on the last Monday in May, the three-day weekend is widely celebrated as the unofficial start of the summer. Millions of Americans travel, host family barbecues, and enjoy outdoor activities this weekend.

Memorial Day is also a great opportunity to explore U.S. culture and history in the classroom.
