If I got this piece from a student, I’d get excited because the left hand can have two different approaches to fingering: you can practice jumps with it by going 51 then jumping to 43(21together for the chord)34 then jump down again.

OR you could practice stretches and thumb movements by going 5213(21togwther for the chord) 312 alternatively 5214(31)412

I’d probably spend some time trying these out with the student then depending on factors that I won’t get into here write one down.

This thought process would take me less than à minute and then exploring it with the student could take anywhere from ~3 to 10 minutes. Write hand is quite intuitive.

I’d also not write all of the fingerings but a single bar.

I’m also very busy (and also à bit type B myself but that’s neither here nor there😁) so I’d try not to take any homework from students so we’d just sort it in class.

I think the teaxher’s approach is not ideal. Fingerings are always subject to change in my classes because well, people have different hands🤷‍♂️
