Resumen
Este estudio verificó cuáles eran las estrategias de estimación numérica de cantidades realizadas por niños en una escuela pública y cuáles eran las más frecuentes y precisas, a partir de entrevistas individuales semiestructuradas. Se encontraron siete estrategias diferentes, que van desde el conteo exacto simple hasta estrategias más complejas, con estructuras multiplicativas. Los resultados indicaron que los niños tenían mayor frecuencia y precisión en las estrategias de conteo exacto para pequeñas cantidades, manteniendo la alta frecuencia, pero disminuyendo la precisión en el uso de esta estrategia para grandes cantidades. Se concluye que los niños tienden a utilizar el conteo exacto aunque no sea necesario y aunque no sea posible, lo que sugiere la importancia de su enseñanza en la escuela.
