תודה על שיתוף!
I had heard of Shalom Sesame but haven't watched it myself. In keeping with this theme, here are a few more ways to say "תודה", although without subtitles or text until the review-assignment at the end, I'm afraid!
"הלו פנינה תודה"
This still needs to be corrected. The "correct" answer (and the only accepted answer) is אומרים תודה, with "" around אומרים. However this is problematic if you're using the word bank as there are no quotes anywhere. And not only that, why are quotes around "We say" instead of "thank you" like the translation indicates. DuoLingo contributors need to get on this since it's obviously been an issue for a long time.
The necessity/specificity of quotation marks in Duo answers seems to be a problem for at least one other course, too: https://www.duolingo.com/comment/25444370$from_email=comment&comment_id=31089724
If you need the tips and notes:
how to get tips and notes: (My favourite ways are the first two):
(By the creator of the *Memrise Hebrew Duolingo vocab course I'm learning Hebrew Duolingo on Memrise! http://www.memrise.com/course/1031737/ ): organized by skill in one pdf for the whole course: https://www.docdroid.net/JnfmyEV/tipsnotesbackup.pdf
Replace your username where USERNAME is for information on your progress & the tips & notes: https://duome.eu/USERNAME/progress
The whole course tips and notes are here (and the site has one for each Duolingo language): organized by skill individually: http://duolingo.wikia.com/wiki/Hebrew
You can also get them on the duolingo.com site (make sure your browser is in desktop view mode so you can see the other duolingo features like discussions & timed practice (the language clubs were only on the app. Now that they are discontinued, many of us have moved to either or both the Discord Hebrew servers, or the Facebook Duolingo Hebrew learners Facebook page). From discussions you can search for all the discussions in this course (like this one you're reading, as well as see general duolingo discussions). If you can't see discussions on the main screen once logged into duolingo you're not in desktop view.
It is impossible to get this marked “correct” if using the word bank!
Duolingo ought to look occasionally at the Discussion, especially the points that generate a lot of comments, it would help them improve the course and iron out bugs. It would help if it were possible to choose from a larger list of issues or write your own comment. (Very often I want to say “The English sentence given is unnatural or incorrect” but there is no option to do that...)
I tried this and the למה אומרים שלום in several different permutations: with quotation marks, without them, with them placed differently. For some reason the computer puts the last quotation mark incorrectly at the beginning of the sentence in the provided answer, and it doesn't accept my answer, for which they were placed correctly around תודה and שלום, respectively. Using a Macbook Pro, Mohave 10.14.6, and Safari 12.1.2.
