Resumo
Este estudo verificou quais foram as estratégias de estimativa numérica de quantidades realizadas por crianças de uma escola pública e quais foram as mais frequentes e as mais precisas, a partir de entrevistas individuais semiestruturadas. Foram encontradas sete diferentes estratégias, que variavam de simples contagem exata até estratégias mais complexas, de estruturas multiplicativas. Os resultados indicaram que as crianças apresentaram maior frequência e precisão em estratégias de contagem exata para pequenas quantidades, mantendo a alta frequência, mas diminuindo a precisão no uso desta estratégia para grandes quantidades. Conclui-se que as crianças tendem a usar a contagem exata mesmo que isso não seja exigido e mesmo que não seja possível, sugerindo a importância de seu ensino na escola.
