If you or your children are about to start an advanced math or science course, you’ll need a graphing calculator. These handy machines have a large screen, ideal for displaying graphs, and allow you to enter multiple equations and handle complex calculations. They cost a lot more than the scientific calculators you may have used in the past, so be prepared for a little shock. To make sure you spend your money on the model that best suits your needs, read on for specific buying criteria and our top recommendations.
The best graphing calculators
What to consider?
Graphing calculators have more advanced capabilities for higher-level math than scientific calculators, with larger, more dynamic screens for graphing functions and plotting coordinates. Before you shop, it is essential to consider the age of the person you are buying for and their grade level, if applicable.
Besides graphing calculators designed to handle middle school algebra to calculus, mathematical calculators for upper-level students are available in two types, while primitive models, which are only useful for skimming the surface of advanced concepts, are not suitable for young children.
You can opt for a model that specifically matches what your child will be learning. In addition, teachers may recommend using a specific brand and model, especially for students in smaller grades. For older high school students, keep in mind that we accept some calculators for various AP and college entrance exams and others are not. There are some models that are more suitable for specific tests than others.
Graphing calculators come with black-and-white or color LCD screens, many have rechargeable batteries and offer USB connectivity, and some come pre-loaded with apps.
