For tracking resources that are used up one at a time and are then completely replenished (e.g. ammunition, rations--as opposed to resources that are reduced and regained in variable amounts like HP) you could do a "hangman" drawing where you draw one line for each thing. This keeps the marks concentrated in one area so you can erase them all in one go.
e.g. If you had 5 things, you could draw a star, and then erase it when it's replenished.
