I completely agree with [Joe's answer](https://parenting.stackexchange.com/a/18639/9826) 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](http://en.wikipedia.org/wiki/Fractal) 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.
