This work is the result of a survey of teachers of Freshwater municipalities and Joaçaba, both of Santa Catarina Midwest, where they collected data on the learning difficulties of students in the first segment of elementary school from mathematics discipline. This research revealed that the operation of subtraction is one of the most difficult content to be taught. Hence, the problem: "As a continuing education course for the early years teachers can help in working with the concept of subtraction?". Thus, based on the conceptual understanding of theories by Liping Ma, it was constructed the course of conceptual learning, and the decomposition and the use of numerical straight main tools for this. The use of motivating factors for the topic discussed reach students and sensitize teachers to use the practical proposals for their classes. The course consists of 12 hours of discussion and 30 hours of practice with students; the application of the topics covered will not be restricted to that period. The emphasis of the course is to provide to students the opportunity of building, in the field of their minds, the necessary conditions to learn subtraction and connect this topic with other important topics of knowledge. The results were analyzed interpretively, of qualitative nature, with applied purpose. In this work we report and comment all the stages of this process.
