Drawing guides are a pain in PowerPoint (when you need to move an object close to the grid, you always end up moving the drawing guide line by accident). Also, grids can change from slide to slide.

My solution, quickly plop in some dummy shapes that define the grid for the slide you are working on. With snap to shape, you can create the slide layout you need, and get rid of the temporary shapes when you are done.
