Graphing Calculators BUYING GUIDE

  • KEY CONSIDERATIONS

    Capabilities

    Graphing calculators will vary in the type and amount of functions it is capable of computing. For example, calculators for high school students will have more limitations than those for engineers. Advanced products will offer thousands of capabilities such as graphing functions, lines, parabolas, cubic functions, etc. Additionally, the best products feature specific keys, such as a fraction key, to make input much faster. Many graphing calculators will list on its specification’s page if it has the functionality for certain math, science and engineering courses.

    Ease of Use

    These computing devices can have large learning curves. Many products — even basic devices — can require hours of use before fully understanding the features, tools and interface the device boasts. During our research, we carefully evaluated the simplicity of the calculator’s interface. Some products, such as the TI-84, require a large learning curve but are common among U.S. high school teachers who teach students how to use the calculator in the classroom. Many products come with extensive user manuals, but be aware, as some user manuals can be dozens — if not hundreds – of pages long.

    Display

    As you enter in equations, you need large displays that allow you to see all variables. Large display screens are ideal, and some products offer color capabilities as well, allowing you to color-code and create easy-to-read graphs.

    Battery Life

    Look for products with rechargeable batteries. Many products require four or more batteries to run and can only last for up to 100 hours on a single set of batteries. Short battery lives not only require many additional battery purchases, but you run the risk of losing power during exams.

    Available Memory

    Look for graphing calculators that offer an ample amount of available memory. This user-available memory allows you to enter and store specific functions and programs into the calculator. You can store functions you are currently working on or those you wish to come back to at a later date. The amount of memory available ranges from just 24 KB to more than 100 MB.

  • PRICE BREAKDOWN

    Graphing calculators vary greatly in price. The more you pay for this type of device, the more functions, built-in applications and design features you will receive. Products less than $100 typically offer your basic graphing features. You can complete equations and functions, but the display is small, memory is low and there are numerous limitations on its capabilities. Products ranging in price from $100-$200 are generally what you will spend on a quality product for a high school or college math student. These products provide all the features you need to complete most functions and will last you several years and through multiple math courses. Products greater than $200 are ideal for professionals and those in graduate math, science and engineering courses. These graphing calculators can perform hundreds of functions, offer the greatest amount of memory, and feature large, backlit color display screens.
