When teaching the course in April 2023 I wrote a table on the board with the prefx length and the corresponding interesting octet of the subnet mask:

 8  16  24      0
 9  17  25    128
10  18  26    192
11  19  27    224

et cetera.

I could also include the cheat sheet made by Jeremy Stretch: https://packetlife.net/media/library/15/IPv4_Subnetting.pdf
