A Good method of teaching

It was crazy, yesterday me and my friend were riding around campus and this girl we are friends with wanted to try. So at first we both stood on two sides of her and walked with her…but that didn’t seem to help her out much. So i got on my uni and came up next to her…within 5 minutes she could ride w/ the support of me riding next to her (w/ her hand on my shoulder and my hand supporting her at her elbow)…and mean like ride a good 200-300 ft. I think this might be a very effective way of teaching someone how to ride…try it out w/ someone who can’t ride. The more we rode the less she depended on me.
