The deadline to file income tax returns here in the U.S. is less than one week away. If you have high school students, some of them may be filing taxes (or having parents do it on their behalf) for the first time. That may lead to all kinds of questions about why we have taxes, the way taxes are calculated, and types of taxes. Crash Course has a twelve and a half minute video in which those questions are addressed.
At over twelve minutes long this is one of those videos that despite being full of good information, students will tune out unless given some specific things to watch for in the video. EDpuzzle and TES Teach are good tools that you could use to build some questions into the video before you share it with your students.
