gecKo mathematics is a system based on the English translations of a Korean arithmetic series used for grades 1-6 in the national curriculum of Korea in 1993-1996. The translations were produced with permission from the Korean Ministry of Education, and with funding from the National Science Foundation.

Block Learning and Conceptualization: Foundations of gecKo mathematics

In gecKo mathematics, constructs are built on a foundation of blocks. As each function is introduced, its relation to previously learned mathematics functions is developed. Concepts are developed in-depth all in one place. Procedures are tied to the underlying mathematical principles.

For example, division is learned in Grade 2-2. During this lesson, the previously learned concepts of dividing into equal parts and repeated subtraction are used to develop a focus on the inverse relationship between multiplication and division.

Teacher's Manuals

Each level of gecKo mathematics contains a concise manual to guide teachers through 9 or 10 units of instruction on the same 5 domains recommended by the NCTM as important school content. Each unit or chapter in gecKo mathematics contains 6 to 10 fully developed lessons.

  1. Outline of the chapter
  2. Study Sequence
  3. Chapter Goals
  4. Development Plan
  5. Evaluation Notes
  6. Text Study: a mathematically rich guide which reviews the concepts contained in the chapter at a more theoretical level than is found in the student texts.
  7. Detailed development of the 6 to 9 lessons in the unit.
