Singapore Math focuses on the mastery of a limited number of concepts each school year. They teach the how and why of foundational math through the use of manipulatives. Students start with the concrete (disks, markers, balloons, etc.) to learn the concept. Then they move to the pictorial stage, where the picture is presented to them or they draw the picture to help represent the problem. Finally, students move to the abstract phase, understanding the problem without the use of manipulatives. The country of Singapore, where Singapore Math comes from, has been ranked among the best mathematically since 1995. Students who were taught Singapore Math in the US have an equivalent of one month’s gain over other students.
