Resumo: It is a bibliographical review about the knowledge produced on number estimation in the last three decades, in order to highlight its importance as a mathematical ability. It was observed that five main aspects are being discussed: their possible mental bases, their relation with the mental representation of numbers, the use of strategies and the ways of evaluating their performance (numerosity and number line estimation). The results indicate that the subjects have different forms of mental numerical representation and task resolution strategies involving number estimation, demonstrating that the strategic process is dynamic and that it is constructed by the subject according to the factors involved in the presented situation. It is concluded that the number estimation should be considered a mathematical skill necessary for success in adult life, having space for discussion in the school.

Observou-se que estão sendo discutidos cinco aspectos principais: as suas possíveis bases mentais, a sua relação com a representação mental dos números, o uso de estratégias e as maneiras de avaliar o seu desempenho (julgamento de quantidades e estimativa na reta numérica). Os resultados indicam que os sujeitos possuem diferentes formas de representação numérica mental e de estratégias de resolução de tarefas envolvendo estimativa numérica, demonstrando que o processo estratégico é dinâmico e construído pelo sujeito de acordo com os fatores envolvidos na situação apresentada. Conclui-se que a estimativa numérica é considerada, pelos estudos revisados, uma habilidade matemática necessária para o sucesso na vida adulta, devendo, portanto, ter espaço de discussão na escola.Universidade Estadual de Campinas2019-12-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoinfo:eu-repo/semantics/otherapplication/pdfhttps://periodicos.sbu.unicamp.br/ojs/index.php/zetetike/article/view/865238910.20396/zet.v27i0.8652389Zetetike; Vol. 27 (2019): Publicação Contínua; e019025Zetetike; Vol. 27 (2019): Publicação Contínua; e019025Zetetike; v. 27 (2019): Publicação Contínua; e0190252176-1744reponame:Zetetiké (Online)instname:Universidade Estadual de Campinas (UNICAMP)instacron:UNICAMPporhttps://periodicos.sbu.unicamp.br/ojs/index.php/zetetike/article/view/8652389/21923Brazil; ContemporaryBrasil; ContemporâneoCopyright (c) 2019 Zetetikehttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessDuro, Mariana LimaDorneles, Beatriz Vargas2024-01-08T14:57:58Zoai:ojs.periodicos.sbu.unicamp.br:article/8652389Revistahttp://www.fe.unicamp.br/zetetike/PUBhttps://periodicos.sbu.unicamp.br/ojs/index.php/zetetike/oaizetetike@unicamp.br2176-17440104-4877opendoar:2024-01-08T14:57:58Zetetiké (Online) - Universidade Estadual de Campinas (UNICAMP)false
