**CALCULATOR BUYER'S GUIDE**

Note: For all courses phones, I-pods, cameras, and other electronic devices will not be permitted for use as calculators. You will need an actual calculator. Bring your calculator to class every day.

__Algebra 1__

For these courses you will need a simple calculator. Just about any calculator will do (even one from the dollar store). I would highly recommend choosing a model with a square root key. If you are planning to take Geometry after these courses, check the guidelines below so you can get a calculator that will work for those courses as well. If you are planning to take Algebra 2, you might want to check those guidelines as well.

__Geometry__

For this course you will need a scientific calculator. You will know your calculator is scientific if it has these keys: "sin", "cos", "tan". You don't need a graphing calculator (the ones with the larger screens) for this course, although if you are planning to take Algebra 2 in the future you might as well read the guidelines below and get one now. New scientific calculators usually run in the $10 to $20 price range, although I have seen them at dollar stores on occassion.

__Algebra 2, Algebra 2/Trig, Advanced Math Topics__

You will need a graphing calculator (the ones with the larger screens) for this course. Just about any graphing calculator will work for most applications, although I strongly recommend certain ones over others. The reason for this is that I'm much more familiar with particular models than other ones, so I'll be able to do a much better job assisting students using calculators that I am more comfortable using.

## Top Recommendations:

Most of the time I will be using a TI-83 for in class demonstrations. Students with these calculators will be able to follow what I'm doing exactly. Click on the pictures to see a larger image.

## Pricing:

Graphing calculators can be expensive, but there is no reason to pay full price for one. Check amazon or craigslist for used calculators, or ask friends and family members. I often use my older brother's calculator which he purchased in 1990 and it works fine for most applications.
