Mathematical Olympiads for Elementary and Middle Schools (MOEMS) is a worldwide year-long math competition. Created in 1977 by Dr. George Lenchner, an internationally known math educator, the Math Olympiads went public in 1979. Last year nearly 150,000 students from 6,000 teams worldwide participated in the Olympiads. All 50 states and about 30 other countries were represented.
There are two divisions, Elementary and Middle School. Elementary level problems are for grades 4-6 and Middle School level problems are for grades 7-8, though 6 graders may participate in Middle School problems. The highlights for students are the five monthly contests, given from November to March. No traveling is required. These contests provide an incentive for students to intensify their study of math.
