  We present a method to measure the weak phase gamma in the three-body decay
of charged B mesons to the final states D K pi0. These decays are mediated by
interfering amplitudes which are color-allowed and hence relatively large. As a
result, large CP violation effects that could be observed with high statistical
significance are possible. In addition, the three-body decay helps resolve
discrete ambiguities that are usually present in measurements of the weak
phase. The experimental implications of conducting these measurements with
three-body decays are discussed, and the sensitivity of the method is evaluated
using a simulation.
