We study the effect of mumerical integration in Finite Element Methods for nonlinear sobolev equations and give some sufficient conditions on the quadrature scheme to ensure that the or- der of convergence is unaltered in the presence of mumerical integration.Optimal L2and H1 esti- mates for the error and its time derivative are established.
