Use the "Graph Paper Tool". Hold down CTRL for perfect squares, else just drag it however you want it to look. You set the "Columns" and "Rows" before you create it (upper left menu in 11).
Once created you can "Ungroup" it and alternate the colors in a checkerboard fashion.
For smaller squares (tapered) use "Perspective" before you ungroup it. You'll have to use Perspective on both axis' in order to get "squares" again. Takes some fiddling. Again, if you hold down the CTRL key while adding perspective it should Constrain the movement horizontally or vertically.
