We consider a discrete time analog of G-expectations and we prove that in the case where the time step goes to zero the corresponding values converge to the original G- expectation. Furthermore we provide error estimates for the convergence rate. This paper is continuation of Dolinsky, Nutz, and Soner (2012). Our main tool is a strong approximation theorem which we derive for general discrete time martingales.
