En este artículo presentamos resultados de un estudio sobre la enseñanza del cálculo estimativo para la multiplicación y la división. Los análisis preliminares permitieron inventariar y analizar la variedad de problemas en diferentes fuentes y a partir de variaciones de los mismos diseñamos una secuencia de 14 clases para 5to año de la escuela primaria. El estudio se centró en los conocimientos puestos en juego por los alumnos, en las intervenciones didácticas y en las interacciones en las clases. En este trabajo se documentan y analizan en particular las dificultades a las que se enfrentaron los alumnos y los procedimientos usados, tanto correctos como incorrectos, cuando resuelven problemas que implican anticipar si un cociente será mayor...
