Paths to the Math Olympiad (AMC 8 vs. Mathcounts)
Given the rising enthusiasm for elite math competitions in recent years (spurred in part by the impressive achievements of the U.S. Math Olympiad Team, which has secured five wins at the International Math Olympiad since 2015), it’s an ideal time to explore the differences between the most popular math tournaments in the U.S. for elementary and middle school students. Among these, the AMC 8 stands out as a leading contest that draws thousands of participants annually, though enrollment in other competitions opens up even more opportunity for students to improve their skills.
In this article, we will showcase representative AMC 8 problems and solutions, providing valuable practice for those seeking to enhance their quantitative abilities or advance to higher levels. For students also interested in broader preparation, we will also discuss the Mathcounts competition and how their practice problems compare with the types of questions found in the AMC 8. We'll also discuss how these competitions fit in with rigorous math olympiads, and how students can begin preparing from a young age for a chance at participating in high school tournaments.
What elementary and middle-school math competitions are available?
The many available competitions for younger students include Math Olympiads for Elementary and Middle Schools (MOEMS), Mathcounts, and the American Mathematics Competitions (AMC) series, including the AMC 8. Of these, the AMC sequence is the oldest and the most highly respected.
What is the Math Olympiad?
The Mathematical Olympiads is a premier worldwide math competition designed for elementary and middle school students, managed by the Mathematical Olympiads for Elementary and Middle School (MOEMS). While the U.S. Math Olympiad Team typically refers to participants in advanced competitions, MOEMS plays a crucial role in developing mathematical skills and problem-solving intuition among aspiring team members at a young age. The purpose of this international math olympiad is to ignite enthusiasm, encourage the creative exploration of mathematics, and strengthen students’ abilities in quantitative problem-solving.
Each year, the competition runs from November to March, with monthly tests administered to teams with up to 35 students. Every 30-minute test may be taken digitally or on paper, according to the convenience of the participating school. Test responses are then submitted to MOEMS for official evaluation and scoring. Achieving a top score can provide valuable experience for students interested in advancing through elite mathematical circles and possibly joining the ranks of the official international competition in the future.
The Math Olympiad welcomes participation from approximately two dozen countries and features two divisions: Elementary and Middle School. Math Olympiad problems at the elementary school level are based on 4th to 6th-grade math concepts, whereas the middle school division focuses on material from 7th and 8th grades. Students in 4th, 5th, and 6th grade may also compete in the Middle School division if desired, helping to prepare them for advanced team qualifiers.
It’s important to note that MOEMS and this Math Olympiad are distinct from the USA Mathematical Olympiad, a challenge reserved for high school students who qualify via the AMC 10, AMC 12, or USA Mathematical Talent Search (USAMTS). The USA Mathematical Olympiad serves as one of the primary pathways for exceptional students seeking a spot on the official U.S. Math Olympiad Team, which represents the country at international events.
What is Mathcounts?
Mathcounts is a premier nationwide middle school mathematics competition held annually at various venues across the U.S. Sponsored by the National Society of Professional Engineers, the CNA Foundation, and the National Council of Teachers of Mathematics, Mathcounts is designed to foster advanced problem-solving skills and mathematical excellence among students. Much like the Olympiads and the prestigious U.S. Math Olympiad Team selection process, Mathcounts engages participants through multiple levels of challenging and interactive “bee” style contests.
Unlike other math competitions, Mathcounts is conducted in person and is widely recognized for its higher level of difficulty. Mathcounts problems span a diverse range of topics, including algebra, geometry, number theory, counting, and probability, offering students rigorous practice and preparation for future contests.
The Mathcounts competition is structured into four progressive stages: school, chapter, state, and national. With each stage, Mathcounts problems become increasingly complex, ensuring that only the most talented mathematicians advance. While perfect scores are more common at the school level, achieving a perfect score on the national Mathcounts level is extremely rare due to the challenging nature of the problems.
Top-performing individuals and teams from chapter competitions progress to their respective state Mathcounts contests. At the state level, only the top four individuals earn the opportunity to represent their state at the Mathcounts National Competition, a leading path for students aspiring to join the U.S. Math Olympiad Team. The coach of the winning state team becomes the official Mathcounts trainer for that state’s national team. At Nationals, all participants tackle both the Sprint and Target Rounds individually, while the top four individuals from each state collaborate in the Team Round, showcasing their collective problem-solving skills on behalf of their state.
By participating in Mathcounts and tackling advanced problems, students build a strong foundation that prepares them for higher-level competitions and potentially leads to selection for elite groups.
What is the AMC 8?
The AMC 8 mathematics competition is a key event in the American Mathematics Competitions (AMC) series, designed to challenge middle school students with advanced problem-solving skills. Part of a suite of contests provided by the Mathematical Association of America, the AMC 8 stands out as the most advanced entry-level math contest on this list, requiring a solid understanding of mathematics. For many students, preparation through Math Olympiad and Mathcounts serves as excellent groundwork before tackling AMC 8 problems.
Aimed at middle schoolers in grades 8 and below who are under 14.5 years old on the day of the competition, the AMC 8 consists of a fast-paced 40-minute test held either online or in-person at a host school. The competition includes 25 multiple-choice AMC 8 problems, covering a variety of mathematics topics such as elementary geometry, probability, counting, proportional reasoning, data interpretation with graphs and tables, as well as coordinate geometry and basic algebra. The test is typically proctored by a teacher or school administrator to ensure a fair environment.
AMC 8 problems are renowned for encouraging creative problem-solving, often permitting several different solution strategies for the same question. Success not only demonstrates mathematical knowledge but also highlights a student’s adaptability and general reasoning abilities.

Students who consistently perform well on AMC 8 practice problems often take the next step by preparing for the AMC 10. High scores can provide an opportunity to advance to prestigious contests, such as the American Invitational Mathematics Examination (AIME), the United States of America Junior Mathematical Olympiad (USAJMO), and the United States of America Mathematical Olympiad (USAMO). Outstanding achievers may even become eligible for selection to represent the U.S. in the IMO.

Final thoughts
Remember, it’s never too early to start practicing your math skills, as there are several options for young, motivated students to explore and develop a passion for competitive problem-solving that can extend into high school and beyond. Whether your goal is to excel in national math competitions like the AMC or Mathcounts, eventually advance to the international level, or simply improve your math knowledge and speed, completing practice problem sets (and timing yourself) is the best way to prepare.
The AMC 8 serves as an introduction to the world of math competitions at the middle school level, and it’s known for featuring elite math challenges. Don’t be discouraged if you don’t answer all AMC 8 practice problems correctly on your first attempt: questions on the AMC are meant to be tough and engaging. Many students find that the AMC exams are among the most challenging math contests they’ve faced so far, but working through problems is also what makes preparing for this exam so rewarding.
