Staff, courtesy of Casio

Spiral and composition notebooks, three-ring binders, protractor and compass, these are the school supplies that you can add to your basket without hesitation. But if you have kids entering more advanced math and science classes, a graphing calculator is likely to appear on the long list of fall must-haves. Generally speaking, they are more expensive – and certainly more complex to cover a wider range of topics – than the scientific calculators used at the start of college. Read on for our top recommendations, as well as how to find the right model and other buying tips before you buy.

What to consider

To start with a few basics, a graphing calculator has more advanced capabilities for higher level math than a scientific calculator, with a larger, more dynamic screen for graphing functions and coordinate plotting. Before you start shopping, it is essential to consider the school year and the school program of the student.

There are graphing calculators that can take a student from college pre-algebra to calculus, but younger ones can be overwhelmed with too many features, and higher-level math students can learn better on a specially designed calculator. for advanced concepts rather than a basic model that just scratches the surface.

You may want to choose something that matches what your child will learn. Additionally, especially in younger classes, a teacher may recommend using a specific make and model. For older high school students, keep in mind that some calculators are accepted for various PA and college entrance exams and some are not, and some models may be better suited for specific tests.

Graphing calculators have black and white or color LCD screens, many have rechargeable batteries and offer USB connectivity, and some come preloaded with apps.
