Abstract

This research aims to identify through the activities applied the difficulties presented by students of the 6th year of elementary school in solving problems involving the operation of subtraction with natural numbers. For this we use based on several authors such as Van de Walle (2009), Toledo and Toledo (1997), National Curriculum Standards (1997/1998), Polya (1995) among others. As for the research objectives was classified as an exploratory qualitative research. As for data collection research we conducted a case study because it allowed a deeper and more detailed study of knowledge. The activity was based on the subtraction of ideas remove, compare and complete. The implementation of the activities took place in June 2015 to 62 students in two classes of the 6th year of elementary school. To help in analyzing the results a questionnaire was also applied. The results indicate that most students can identify the mathematical problems which procedures to be used, but most of them have difficulty when it decides the method of exchange.
