# What is Math methods: Definition and 34 Discussions

Singapore math (or Singapore maths in British English) is a teaching method based on the national primary mathematics curriculum used for first through sixth grade in Singaporean schools. The term was coined in the United States to describe an approach originally developed in Singapore to teach students to learn and master fewer mathematical concepts at greater detail as well as having them learn these concepts using a three-step learning process: concrete, pictorial, and abstract. In the concrete step, students engage in hands-on learning experiences using physical objects which can be everyday items such as paper clips, toy blocks or math manipulates such as counting bears, link cubes and fraction discs. This is followed by drawing pictorial representations of mathematical concepts. Students then solve mathematical problems in an abstract way by using numbers and symbols.The development of Singapore math began in the 1980s when Singapore's Ministry of Education developed its own mathematics textbooks that focused on problem solving and developing thinking skills. Outside Singapore, these textbooks were adopted by several schools in the United States and in other countries such as Canada, Israel, the Philippines and the United Kingdom. Early adopters of these textbooks in the U.S. included parents interested in homeschooling as well as a limited number of schools. These textbooks became more popular since the release of scores from international education surveys such as Trends in International Mathematics and Science Study (TIMSS) and Programme for International Student Assessment (PISA), which showed Singapore at the top three of the world since 1995. U.S. editions of these textbooks have since been adopted by a large number of school districts as well as charter and private schools.
