This paper focuses on young children’s understanding of partitive division when discrete quantities are involved. The study analyses how young children understand the inverse divisor-quotient relationship when the dividend is the same. The participants were 30 kindergarten children (4-5-years-old) from Braga, Portugal. Individual interviews were conducted when solving tasks involving the division of 12 and 24 discrete quantities by 2, 3 and 4 recipients. Results showed that children have some ideas of division, they can estimate for the quotient when the divisor varies and the dividend is constant. Educational implications of these results are discussed for kindergarten activities.
