This work aims to investigate teachers' conceptions of mathematics in 9th grade of elementary school of public schools in the Mamanguape city, Paraíba about using the calculator in the classroom. As there search objectives, this is characterized as exploratory. With respect to data collection, this research is characterized as a case study, which used a semi-structured questionnaire.

As opposed to the use of the calculator argument, a teacher mistakenly says that the calculator does not contribute to learning and not for academic achievement. We suggest finally activities that bring the application of mathematical concepts through the use of the calculator where might recognize satisfactorily in all proposals and facilitate solution development calculator allows students to think, strategize and apply their mathematical knowledge to get the solution thus making the study of mathematics more participatory and interconnected reality.
