I've just found a great page on mormon.org. https://discover.mormon.org/en-us/
This page has a brief explanation of ten basic beliefs of The Church of Jesus Christ of Latter-day Saints (Mormon). If you click on the View Details button, you will find videos about that belief, more detailed explanation, and even have a chat option if you want to discuss that topic with a Church member. It can be a great help if you are teaching your family or others who are not familiar with our core beliefs.
