Abstract
The main purpose of this study is to develop a conceptual understanding of the
irrational number of the square root of 2 ( 2 ). Participants in the study were 20 ninth-grade
male students. Activity Theory was used as a framework to show the development of the
conceptual understanding. Since this study was conducted during the COVID-19 pandemic;
online teaching method was adopted. In this teaching method, WhatsApp messaging and
calculator were used as our basic technology. Virtual education lasted 2 sessions (120
minutes) for the development conceptual understanding of the irrational number of square
root of 2. To produce data, WhatsApp Export Capability was used. For data analysis, the
online teaching activity system was used. By analyzing this activity system, three tensions
were understood. Modifying these tensions, has led to their students making the concept of
the irrational number of the square root of 2 ( 2 ) and reach a single definition
