Free content for Spanish learners (for English speakers)
https://www.youtube.com/channel/UCAL4AMMMXKxHDu3FqZV6CbQ (Easy Spanish) Hands down to this awesome spanish learning channel which supports both English and Spanish subtitle simultaneously along with the video. This is the best thing I have found. These guys conduct authentic spanish interviews with native speakers.
https://soundcloud.com/languagetransfer/sets/complete-spanish (Language Transfer) A free 90 audio podcast series to go through with the Spanish grammar rules easily. The content follows like how to think and form sentences instead memorizing grammar rules. Check out the youtube version of the playlist (if one found difficulty on soundcloud) :- https://www.youtube.com/playlist?list=PLeA5t3dWTWvvwf5fw0Nl7mVk0OUjP1Ln2
https://es.wikibooks.org/wiki/Wikichicos (Spanish version of Wikibooks for children) Since, we don't have a simple version of Wikipedia in spanish but we have Wikichicos. This spanish Wikibooks version is dedicated to children and of course young learners. Helpful tip :- It would be difficult to translate words/sentence frequently, so install Google Translator extension for chrome! where you just need to select the word/sentence (double click) to get the english meaning quickly. Also check Vikidia portal : https://www.vikidia.org/ It is most similar to Wikipedia but for kids.
Other than the awesome feature of Duolingo stories, you can also practice spanish using short stories by free sign up on :- https://readlang.com/ And also go for the handful stories on :- https://www.thespanishexperiment.com/stories
Also, make a habit to learn Daily word of the spanish and a grammar article here :- https://www.spanishdict.com/guide
I hope that is sufficient! I'll repeat :- Do check the first channel at least. I am sure it will be the best thing of your learning day.
I've been using Language Transfer for a bit of time and it's a really interesting way to learn.
