BASIC MATHEMATICS IN ENEM PROOFS

AND EITHER. Elementary arithmetic. Reason and proportion. Account methods gem.

The National High School Examination (ENEM) is currently the main means of access public and private universities in Brazil and a quarter of this test is made up of math questions that address much of the content that should be taught in basic education. Government and International Student Assessment Program data (PISA) reveal, however, that most Brazilian students finish this stage of teaching with low mastery of this discipline, and therefore, unprepared to face approves. In view of this reality, this work presents three mathematical contents that were addressed in at least 30% of the questions in 11 of the latest exams in the ENEM, applied between the years 2009 and 2019, concepts of basic Arithmetic, Reasons and Proportions and Counting Methods. The proposal here is to provide students with wish to prepare for the test and teachers who work with the preparation of these, didactic and practical material that can contribute to the consolidation of these contents m to contribute to the good performance of these students when taking this exam. In each chapter the theoretical part is presented with application in direct examples and also contextualized. In addition, each one ends with a section where ENEM issues were presented with a commented solution proposal.
