This series of talks will review the construction of the GLSM using toric geometry.  We will construct probably the easiest and most complete example of a quantum field theory computation demonstrating mirror symmetry by considering the discriminant locus of singular models. The lectures should roughly proceed as:

1. The nonlinear sigma model and Calabi-Yau manifolds, N=2 supersymmetry and superspace.
2. The U(1) GLSM construction for algebraic varieties
3. Renormalization and phases.
4. Arbitrary Abelian gauge groups and toric varities.
5. Mirror symmetry and the discriminant locus.
