|First set of squares|
So to get the checkerboard, select the frame, then copy, paste in place, and scoot over a bit. My stroke weight was set to 6 pt, and my cursor key nudge (in Preferences) was set to 1pt, so I just had to nudge it over 6 pts and up 6 points and it lined up to make a perfect little checkerboard.

Next, copy and paste in place, changing the color to blue to make it easier to line up. Change the line distance to 60 pt, and the stroke weight, dash length, and gap length to 30 pt. I chose 30 points because I needed a 5x5 set of tiny squares (6 pts each) to fit perfectly inside one of these larger squares.
