The Mathematics Curriculum in Primary and Lower Secondary Grades

A summary follows of the national curriculum guides for mathematics through the eighth grade. The curriculum ensures that students who finish the second cycle of basic education (elementary level, Grades 4 to 6) have the necessary skills and a solid foundation in mathematics. Students must be able to do the following in the mathematics domains described below:2

  • Mathematical reasoning—Find tendencies in a sequence of results and generalize them; extract general statements from specific contexts; establish procedures; and argue by providing an analogy and giving examples and counter-examples
  • Problem solving—Visualize situations and handle information; use and apply mathematics in various domains, especially in technology and other branches of learning; verify results; and use mini-calculators to carry out the four operations
  • Communication—Read, understand, and interpret a mathematical text by translating it into figures, representations, or equations, and translate a given mathematical relation into spoken language
  • Spatial—Represent locations on a map, characterize various plane figures and use geometric instruments to draw them, and develop an understanding of some solid figures
  • Numerical—Master the Indo-Arabic system of numeration; recognize decimal numbers; master all types of calculation, including computational and mental, and learn to use a mini-calculator (for integers and decimals); perform simple operations with fractions; and estimate a result
  • Measurement—Measure perimeter, area, capacity, and angles and use metric units
  • Statistics—Collect and interpret data
