Grade K-2

First Mathematics Challenge🇬🇧The First Mathematics Challenge (FMC) has been specifically created to give all pupils, UK and worldwide aged between 7-9, the opportunity to take part in a fun Mathematical Challenge.
Singapore & Asian Schools Math Olympiad🇸🇬Created in 2006, SASMO is one of largest math contests in Asia. It has expanded from 155 local participants in 2006 to more than 20 000 participants from 19 countries in SASMO 2016. More than 100 schools from Singapore took part in SASMO 2016. The SASMO Team with the support of Advisory Council spend countless hours carefully developing contest papers which will touch on both school and Olympiad maths. This combined effort allow participants to do better compared to pure-Olympiad papers, since they are familiar with some questions and are able to put on their thinking caps for others, bringing out the inner mathematician in them. With realistic and high standards, SASMO contests aim to stretch the untapped thinking potential of the student population, their participation in SASMO will help them improve in school mathematics as well as higher order thinking skills (HOTS).

Grade 3-5

Cyprus Mathematical Olympiad🇨🇾The Cyprus Mathematical Olympiad is a Cyprus mathematics competition for students from grade 3 to 12, organized by the Cyprus Mathematical Society. There are five set of problems, each is for two grades. Note that Cyprus Mathematical Olympiad has nothing to do with the selection process of the national teams of Cyprus.
Think Academy Singapore Math Olympiad🇸🇬Think Academy Singapore Math Olympiad (TASMO) is a math competition organized by Think Academy Singapore in September annually. The competition is open to K2 to P6 students. The test questions are set by a team of experts, including the former coach of China and Saudi Arabia national Math Olympiad team. The questions are based on the seven abilities of calculation, geometric cognition, data processing, abstraction, logical reasoning, practical application, and creative thinking. The competition is suitable for students who have strong interest and aptitude in math. Outstanding individuals and teams will be awarded. The medalists will be invited to global Think Math Competition to represent Think Academy Singapore and compete with top Think Academy students in USA, Canada, UK, Australia, Malaysia.

Grade 6-8

Purple Comet! Math Meet🇺🇸The Purple Comet! Math Meet is a free, annual, international, online, team, mathematics competition designed for middle and high school students that has been held every year since 2003. Teams of from one to six students compete by submitting solutions to a list of mathematics problems. There is a ten-day window during which teams may compete choosing a start time most convenient for them. The problems range in difficulty from fairly easy to extremely challenging.
Grey Kangaroo🇬🇧As follow-on Rounds to the Intermediate Maths Challenge, the Grey Kangaroo is a 60 minute, 25 multiple choice challenge. Entry to the Grey Kangaroo is by invitation based on a qualfying IMC score, or by discretionary entry. Several thousand UK-based students qualify from the IMC each year. Open to UK schools only.
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.

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.
