Is it okay to have these two requests without any joining part, and is this the standard way of expressing it or is a particle being omitted?
"te" basically acts as the "joining part" so yes, this is correct.
Wanted to ask the same thing
I suspect a comma is a natural thing to use between the two requests, but that is lost since we don't get commas in the tiles. I do not know if a particle can be used instead, or whether the sentence is gramatically correct without the comma.
Or at least それから.
also (asking for any japanese speaker)
do people ever write this with a 「て、〇」 or is it just 「〇て〇」？
Some nouns (like まど in this case) are separated into their kanas in the given word-cards in these types of exercises. Is this intentional?
What's turn off in Japanese then?
消す 「けす」to turn off; to erase
There should be a comma or conjunction like それから
て does the "and" function
some kanji have broken audio in this question.
