All of the tree amplitudes are constructed for four supersymmetric theories in six dimensions using spinor-helicity variables and the CHY formalism. Two of the theories, the world volume theories of an M5-brane and a D5-brane, only have nonzero amplitudes when n, the number of particles, is even. The other two theories, (1,1) super Yang-Mills and (2,2) supergravity, have nonzero amplitudes for both even and odd n, of course. The constructions for odd n involve some novel features.
