There are lots of very simple stories, in Ukrainian, on Duolingo. They are not in the Ukrainian course, but in the English for Ukrainians course. In the video below you can learn how to access these stories in about a minute. Be sure to download the one I have typed up for you … A Difficult Problem.

My Big Book of Ukrainian Exercises is available on Amazon, and supports your studies on Duolingo.
