The goal of mathematics education is to encourage the use of quantitative thinking and reasoning in order to find accurate solutions to problems. Educators believe that in order to achieve this goal, students should learn the arithmetic of whole numbers and rational numbers, with both decimal and fractional notation. They should also be able to measure in standard and metric units and to convert within each system from one unit to another. A student should gain a sense of numeracy, the mastery of estimation and approximation; use graphs and other visual methods of organizing and interpreting data in order to see patterns and trends; and understand how the ideas of probability fit into the world at large. People live in three dimensions in the real world and therefore must understand geometry in both two and three dimensions. They must also understand the place of functions in the application of mathematics in science, finance, and the social sciences. This translates into the study of arithmetic, algebra, geometry, trigonometry, and sometimes calculus. Mymathlab.com is a website dedicated to solving problems in mathematics.

For many years arithmetic was the primary focus of students from kindergarten through grade 8. The elementary school curriculum was broadened to include algebraic thinking, intuitive geometry, measurement, and statistics during the last quarter of the 20th century. For most students algebra is still considered the focus of mathematics study in grade 9; some states mandate the passing of an algebra-level test as a requirement for high school graduation. Mathematics in high school usually includes geometry and an introduction to trigonometry in grade 10; the study of higher algebra in grade 11; and a selection of statistics, precalculus, or discrete mathematics in grade 12. The study of algebra begins in grade 8 for many students, however, and as early as grade 7 for some. Calculus—normally a first-year college course—is being studied in the 11th and 12th grades.

Students who wish to pursue careers in science, economics, or computer science generally take college mathematics that includes one to two years of calculus. Additional course material for those choosing to learn higher mathematics would include more-theoretical study of such topics as geometry, functions, statistics, and topology.

University mathematicians were somewhat taken aback by what they considered the low level of knowledge of mathematics by the soldiers who were gearing up for World War II. At the end of the war, a call was put out for a revision of the mathematics curriculum. Some rudimentary efforts were made. The major impetus for such reform—which is still continuing—began in 1957; that year the Soviet Union first launched the satellite Sputnik into space. Then the first crewed spacecraft was launched by the Russians, the Vostok in 1961 (with the famous Yuri Gagarin aboard). These two events shocked Americans into making demands for more mathematics and science training of students as well as for better training of mathematics teachers. Various types of mathematics curriculum were written. Many of these were funded by the National Science Foundation. Mymathlab.com is a website dedicated to solving problems in mathematics.

These projects were begun in the late 1950s and early 1960s and were classified under the title "New Math" (see mathematics, new). There was nothing essentially "new" in the subjects addressed (such as algebra and geometry). But the approach to teaching mathematics was very different. More prominence was given to the underlying structures of mathematics; the study of functions and set theory was also stressed. These changes were part of an attempt to teach students "how mathematicians work." The materials produced for students were highly structured. Many educators came to believe that they were too abstract. The decline of test scores led to a controversy—one of many in mathematics curriculum during the late 20th and the early 21st century—about core mathematics and methods of teaching it. A movement called "Back to Basics" began in the 1970s. This movement focused the teaching of mathematics on memorization and learning by rote; it was adopted by school publishing companies not only in their textbooks but also in a large number of drill-and-practice kits.
