Add ice to liquid water one at a time and measure the temperature of the water once added ice cubes no longer melt.

Reason: when ice and water are in equilibrium during melting/freezing the temperature stays at the melting point (0 °C for pure water). Adding ice until no more melts ensures the mixture is at that equilibrium; measure the temperature of the ice–water mixture (with good stirring) to get the melting point.
