Hong Kong Mathematics Kangaroo Contest🇭🇰MKC is one of the largest mathematics competitions in the world. The contest was first held in France in 1991 and was named “kangaroo” because the contest format drew from the previously held Australian Mathematics Competition. As MKC became very popular among students, the contest has first spread from France to European countries, and has further expanded to around the world. Now, MKC is coordinated globally by “Association Kangourou Sans Frontières” (AKSF). Magic Square Association (MSA) is the official organiser of MKC in Hong Kong as well as Macau. MSA aims to promote the mathematical education in Hong Kong and Macau. To participate in the contest, students in kindergarten, primary, or secondary schools must meet at least one of the following criteria: - Students registered in schools located in Hong Kong or Macau. - Permanent residents of Hong Kong or Macau. - Holders of valid visas issued by the Hong Kong SAR or the Macau SAR government.

Grade 3-5

Bangladesh Mathematical Olympiad🇧🇩Bangladesh Mathematical Olympiad (BdMO) started its journey in April 2001. It's months-long, country wide festivals around mathematics. It is open for school & college going students (upto class XII) of the country. The usual timing of the festivals is around December - February.
ELMACON🇨🇦ELMACON was started in 1999 and is organized by PIMS under the guidance of Dr. Cary Chien (formerly of David Thompson Secondary School), Joshua Keshet, Klaus Hoechsmann (the PIMS Education Facilitator), as well as volunteers from UBC, SFU and the Lower Mainland. ELMACON gives students from grades 5 to 7 a chance to experience mathematics as an exciting sport. The contest is modelled after the successful MathCounts competitions (which are also supported by PIMS), but is aimed at younger students. Students from grades 5, 6, and 7 compete in separate divisions. Each division is comprised of three rounds Sprint, Target (both written) and Countdown (a verbal one-on-one competition). The top 25 participants in each grade are acknowledged and the top ten participants from each grade advance to the CountDown Round (oral contest).

Grade 6-8

Gauss Contests🇨🇦The Gauss Contests introduce students in Grades 7 and 8 to a broader perspective of mathematics than their school curriculum can typically provide in a fun, accessible way. Intriguing problems and a multiple-choice format make the Gauss contests a wonderful opportunity for all participants to grow their interest in and curiosity about the power of math.
Acton-Boxborough Math Competition🇺🇸ABMC is uniquely designed such that every participant can solve a sizable portion of the problems. The difficulty ranges from that of simple arithmetic, algebraic, and geometric problems to that of the AMC. All participants will have problems they can solve and problems that will challenge their mathematical problem-solving skills. The competition was designed with the intent than any student will have a chance to succeed in math. The onsite competition is in April and consists of speed, accuracy, and team rounds. Trophies, medals, and prizes are awarded to high-performing individuals and teams. Additionally, ABMC provides free monthly online contests in October, November, and September. ABMC was founded by Akshay Gowrishankar, Allen Wang, Antonio Frigo, Richard Huang, and David Lu in 2016.
Kenya Mathematical Olympiad🇰🇪The Kenya Mathematical Olympiad is an annual Secondary School mathematics contest organized by the Mathematics Association of Kenya in conjunction with the School of Mathematics, University of Nairobi. The competition is organized with the aim of selecting Kenya’s teams for the International Mathematical Olympiad and the Pan African Mathematical Olympiad. Every secondary school with eligible students can participate and is encouraged to do so. The Competition is open to both Junior and Senior categories.

Grade 9-12

Baltic Way Mathematical Contests🌍The Baltic Way team competition is held on the shore of the Baltic Sea every autumn since 1990. The name of the competition comes from the mass demonstration for the freedom of the Baltic States organised on August 23, 1989, when people from Estonia, Latvia and Lithuania stood hand in hand along the road from Tallinn to Vilnius. The rules of the competition are simple: each country sends a team of 5 high school students, who are expected to solve 20 problems within 4.5 hours. During this time, the team members can and must communicate — otherwise they would not be able to solve such a quantity of problems. Hence, Baltic Way is not only about mathematical knowledge, but also about cooperational skills. For the first two years, only teams from Estonia, Latvia and Lithuania took part in the event, but later all the other countries surrounding the Baltic Sea (and also Iceland) joined in. Thus, the contest is now normally held among 11 teams: Denmark, Estonia, Finland, Germany (represented mainly by Rostock and Hamburg), Iceland, Latvia, Lithuania, Norway, Poland, Russia (represented by St. Petersburg) and Sweden. Sometimes organisers also invite a guest team to take part in the contest. In 2001, there was a guest team from Israel, in 2004 and 2014, from Belarus, in 2005, from Belgium, in 2011, from South Africa, in 2015, from the Netherlands, and in 2021, from Ireland.
European Mathematical Cup🇭🇷The European Mathematical Cup (abbr. EMC) is a high school mathematics competition organized by the Croatian association Young Gifted Mathematicians Marin Getaldić in cooperation with various wonderful professors and university students who help organize the competition internationally. The competition is divided into two categories: Junior (students younger than 17 on the day of the competition and who have never participated at the IMO) and Senior (other high-school students or exceptional elementary school students). A student who satisfies the criteria to compete in the Junior category can choose to compete in the Senior category instead. The duration of the competition for both categories is 4 hours. Within that time, the students attempt to solve 4 problems, one from each of the following areas: algebra, combinatorics, geometry and number theory. Modelled by the rules of other international competitions such as the IMO, the only instruments permitted in the competition are the writing and drawing instruments. The use of formulas, calculators and other instruments is prohibited. In terms of required knowledge, the problems are similar to the IMO problems, albeit the problems of the Junior category are usually more elementary and require less knowledge.
Alberta High School Mathematics Competition🇨🇦The Alberta High School Mathematics Competition (A.H.S.M.C.) is an annual mathematics competition for high school students in Alberta. The A.H.S.M.C. consists of two Rounds. The students write the contest in their own schools. Calculators are not allowed. The First Round is an 80-minute paper, consisting of 16 multiple-choice questions. The Second Round is a 3-hour paper, consisting of 5 problems requiring full solutions.
