Let's start by understanding the structure of a chessboard that consists of 64 squares.

First, remember the positions of the light and dark squares.

The center: d4, d5, e4, and e5

The 8 x 8 grid consists of the four 4 x 4 grids.

The 4 x 4 grid consists of the four 2 x 2 grids.
Thinking of 2 x 2 squares as a unit helps you to locate the light and dark squares.
