This puzzle is rated 2 star (easy).
I do like my vintage puzzles and here is another,,,
The humble chessboard is basically an 8 by 8 grid. Many people refer to it as having 64 squares, but on an 8 by 8 grid I could very easily draw squares that are 2 by 2 and 3 by 3... even some that are larger!
In total, how many squares are there on a chessboard?
