This system is designed to build a foundation of arithmetic theory into students that will position them for more advanced math. The way Singapore does this is by first introducing students to a few key concepts with concrete examples and pictures. Then, the student is led progressively and logically to understand the abstract concept. (This Asian model is a direct inverse to math educational practice in the U.S. where many concepts are taught during the early years progressing to just a few by the upper elementary and middle school levels.) Singapore Math is a pleasing balance between drill and creative problem solving. Those who have compared SM with other math curriculum report that Singapore math moves the students more quickly and rationally toward abstract concepts. There is an emphasis on homework and practice, and an effective mix of word problems, drills and mental calculation. Instruction is paced to the needs of each individual student.
