**Title:**Counting Lattice Points in Polygons

**Abstract:**If you draw a polygon on a grid, you can try counting the grid points (also called lattice points) insie the polygon. This simple problem is at the heart of many deep ideas in combinatorics and optimization. We’ll work out some basic examples, and see surprising connections to geometric series, the computation of area, clever ways to chop up regions into weighted regions. Be prepared to count!
