Hi ontheedgeofwhatever:
DD1 wouldn't have been able to read any of these when she was at start of Y2 - also expect she would have stumbled on 'ph' = 'f' sound. DD1 was still pronouncing spheres (her maths group) as suff - ears in late Y3. [NB phonics only just introduced when DD1 in Class R and teacher wasn't exactly highly trained/ convinced about this scheme].
DD2 now starting Y3 can read these words - but again, not completely certain that at start of Y2 she would. She was put through the jolly phonics system from beginning of class R, but I don't think they were working at the recommended rates.
I've found a list of scheme for teaching sounds through jolly phonics system here www.nonweiler.demon.co.uk/How%20JP%20fits%20with%20L&S%20Phases.pdf.
According to this scheme the 'ph' sound is meant to have been taught at the beginning of year 1 (see top page 4) and belongs to phase 5 of the six phases of phonetics taught through this system, presuming that this commences beginning of YR.
So - I'm not totally surprised the Y2 teacher has the expectation that your child should be able to do this, but slightly
about how he or she has communicated this to you, so early in the year.
I think this note is just rushed, but possibly a good idea to try and talk to the teacher about your DC's reading level and what you need to be working on at home. Ask if she'd recommend the jolly phonics work books or if the school has work sheets/ on-line resources they can suggest/ provide.
I know that my DD2 had a real stumbling block on moving from one and two syllable words to longer words, also further complicated by the fact that this coincided with moving up to 'Chapter Books', with fewer illustrations, which can seem daunting as well. So although she could pronounce individual phonemes, she couldn't string them all together initially.
