Down-Ward Spiral
I never noticed it until BeyondDC posted about it, but the Wards are numbered in a clockwise-pattern:
I use the trick in the image at right to keep track of wards. It’s simple: Starting with Ward One in the center of the city, drawing a clockwise spiral results in a line that goes through the wards in ascending order.
If you can remember the spiral, you can remember which ward is which.
I ended up surfing over to Wikipedia to see another map and I read that there are 127 neighborhoods in D.C.:
The District of Columbia is divided into eight wards and 37 Advisory Neighborhood Commissions (ANCs) within these wards. The total number of named neighborhoods is 127.
I’m filing that away for trivia night.
