Hey MMMers

I'm a math teacher, and on Friday, I'm starting a 6 day project with my STEM Algebra 2 class on FIRE, using what we've learned about exponentials and statistical analysis to create retirement projections.

For day 1, I to do their own analysis and determine the growth rate of Stocks, Bonds, Housing, and Gold, using historical data.

I have data for everything...except BONDS. Can anyone help by giving me a link to a website that shows year vs bond price of some total bond index? I feel like it shouldn't be hard to find, but I can't find it. **For example, Vanguard Total Bond...what price was it selling for on January 1 for the past 20 years? Or something like that. **

I'll keep looking, but any help would be appreciated.

**Here's the Project Daily Plan, for those interested:**

**Day 1:** Compare a few asset Classes....Stocks, Bonds, Housing, Gold.

**Day 2: **Explore the Trinity Charts and learn how to read them + the Shockingly Simple Math of Early Retirement Chart from MMM

**Day 3-5:** Pick two careers. Find research their pay. Run the numbers for a 10%, 20%, 30%, 40%, 50% savings rate to see how much you'd have to live on to retire in various numbers of years.

**Day 6:** Present your data to the class for your two careers/savings rates, and explain what career/savings rate combo you'd pick if you had to choose today.
