Take the time to learn your bass clef. You have some "key notes" - C below middle C, the clef itself highlights F below middle C (the fat dot that starts the symbol), and you have middle C. I worked on 5 notes at a time using an introductory Czerny that introduced them that way, naming the notes while I played them, and staying aware of which piano keys they were. Btw, Czerny wrote a series of letters to a young student whom he was advising at a distance: she had a daily teacher as well. He basically told her that learning the notes was a pain in the neck and the sooner she got it behind her, the easier it would be for her. He had her write out what she had played every day, so that the notes would stick. I've never tried it myself.
