I have a page on my website that might be helpful to you. To go find my website, use the easy-to-spell and easy-to-remember link www.mathinlivingcolor.com. At the very bottom of this page, there is a link that will take you to my Homepage.

Once you are on my Homepage, look for the link near the bottom of the page called "Tech Prep". Choose the link "Percents." There you will find a non-traditional explanation that my own students, before I retired, found a lot easier to understand than the published textbooks of that day.

Everything on the website is FREE. If you find something you really like, just print your own copy of it!!

If anyone needs to contact me, especially about the website, my Email address is rapaljer@seminolestate.edu. I'll be glad to help you find an explanation on my website to help you with your algebra topic!
