I completely agree with Joe's answerJoe's answer but wanted to add an example from my experience.
I found math in middle school and high school to be as boring as rocks. I was lucky, because my dad bought back some books on fractals and I could use some programs (and write some myself) to see how math was involved in:
- the Mandelbrot set
- measuring the coastline or fractal dimensions
- the shape of mountains (e.g., landscape generator programs)
- snowflakes
As it turned out, with a bit of programming, I wrote some programs for a few fractals and my math teacher was willing to let me give a little presentation to my class.
Much cooler than simple algebra problems.
So my advice is to figure out how to make math more interesting. Why does she find it boring?
And, as my example illustrates, maybe find some examples or branches of math she won't find boring.
- Topology (studying knots, surfaces, computational geometry)
- Fractals
- Chaos theory
- Predicting the stock market / machine learning
- Statistics
There are lots of great possibilities. I also really enjoyed reading the history of mathematics - some weird and crazy characters along the way.
