Hello Priscilla Portis - Debbie Coldiron has made some great suggestions below. Based on my experience (& preference), the beginner series videos by Celest Pereira & Siri Peterson Cavanna would be a great start. They explain the basics without making the beginner feel overwhelmed.

Hi Priscilla Portis. Welcome to Grokker!

I've attached a few beginner yoga/flexibility workouts that you may enjoy. In addition, you may want to consider joining a beginner yoga program. Programs are a great way to take the guesswork out of which workout you should do on what day. Here are some good beginner yoga programs, as well as some programs on flexibility:
