Mathematics

To prepare today’s elementary students for tomorrow’s world, the goals of our mathematics curriculum must be appropriate for the demands of a global economy in an age of rapidly increasing information. The National Council of Teachers of Mathematics has identified five broad goals required to meet students’ mathematical needs for the 21st Century. Students must:

  • learn to value mathematics
  • become confident in their ability to do mathematics
  • become mathematical problem solvers
  • learn to communicate mathematically
  • learn to reason mathematically

In order to reach these goals, we provide a balanced program of skills, concepts, and problem solving. Mastery of whole number computation is expected by the end of the Fifth Grade, but we expect the underlying understanding of the concepts as well, not simply rote memorization of the algorithms. This is why our mathematics curriculum actively involves children in doing mathematics. Children are encouraged to explore, develop, test, discuss, and apply ideas. Classrooms are equipped with a variety of physical manipulatives, such as counters, interlocking cubes, base-ten blocks, attribute and pattern blocks, tiles, rulers, geoboards, graphing grids, and balances. These materials help to provide a strong conceptual framework that allows children to acquire skills in ways that make sense to them.

Problem solving is emphasized at every level. First and Second Graders learn to reason mathematically through discussion of stories and problems that not only entertain the children but challenge them to think carefully. The stories are filled with surprises, so children cannot just routinely use arithmetic to solve the problems. Instead they must be able to draw upon all their mathematical knowledge and common sense and attention—just as adults do in solving problems in real life. Children also learn specific strategies, such as guess and check, make a drawing or act it out, and look for a pattern. Third and Fourth Graders add to the repertoire of problem solving strategies they learned in lower grades, while Fifth Graders participate in the Math Olympiads problem solving contest. Preparation for this contest requires writing skills and fosters cooperative work and much enthusiasm for problem solving.

Our curriculum includes a broad range of content at every level. In addition to number sense and basic computation, we also include measurement, estimation, mental math, geometry, statistics, and probability. We want children to see the interrelated nature of mathematical knowledge, and to learn that mathematics can be applied to a wide variety of real world problems. We therefore integrate mathematics into other areas of study, such as measuring in a science lesson or writing to help clarify mathematical thinking. Learning stations, games, open-ended problem solving, and activities of varying levels of difficulty are designed to meet the needs of students at all stages of mathematical development.

Technology also has a place in the mathematics education of young children. Calculators enable children to explore number ideas and patterns, to have valuable concept-development experiences, and to focus on problem-solving processes. Calculators do not, however, replace the need to learn basic facts, to compute mentally, or to do reasonable paper-and-pencil computation. Children must learn to recognize when use of a calculator is appropriate and to recognize when computed results are reasonable.

Computers are also used at all levels, both in the classroom and in the two computer mini-labs. Students explore problem solving, graphing, and computation using a variety of software and Internet sites. Computer simulations of mathematical ideas, such as modeling the renaming of numbers, are important aids in helping children identify the basic concepts in mathematics.
