Check out ideas.classdojo.com for super inspiring videos that teach students about growth mindset and empathy. These are perfect videos for the elementary school age group -- and there are even Korean subtitles if students don't fully understand English yet. These videos had a huge impact on my student's motivation in the classroom and empathy towards others.
There are also great discussion questions and lessons that go along with the videos that have been a huge hit .Couldn't recommend more!
