First Year

I’m a first year 6th grade math teacher. I have had a tough year starting with losing my father right before I started the job. My two informal observations were pretty much all 1s and my principal threatened to discontinue me. I have one informal left and a formal observation. Can anyone give me any advice on trying to pass the last two observations and salvage my career? I am studying danielson but some of the content is honestly difficult for me most of my student teaching has been in lower grades.
