Grade Appropriateness

I’ll discuss more about incorporating a calculator into childhood education later in the guide, but for now here are the usual grade appropriateness “standards.”

Graphing calculators become almost mandatory for most 9th grade students.

Calculators Allowed on the SAT

This is a common concern when buying a school calculator, but there is very little to worry about. During the math portion of the SAT/PSAT, students can use any calculator with two exceptions. The calculator cannot have 1) a QWERTY keyboard or 2) paper tape.

The Best Non-Graphing Calculator for Engineering, Chemistry, & Computer Science

Regular ‘Scientific’ Functions on your calculator

Without even tapping into their graphing capabilities yet, it is important to realize that graphing calculators offer a large advantage over regular scientific calculators. The nature of their display allows for a much more intuitive flow of work. Students are able to see each line that was completed, and can actually copy and paste values of calculations from previous lines of work. This becomes extremely valuable in many applications of difficult math problems, not to mention physics, math, engineering, statistics and even some branches of biology. When problems require multiple steps and a variety of numbers that are very large, very small and/or contain many decimal values, storing answers becomes an essential skill.

Graphing Capabilities

Of course, it is the graphing capabilities that most students want to make use of when they are first using a graphing calculator. Students are usually quite amazed at how easily they can graph a function, and wonder why nobody showed them this sooner!

The reality is that students first need a solid understanding in the paper-and-pencil art of graphing before taking the plunge into a graphing calculator. Through the use of algebra equations, tables of values of ordered coordinate pairs, and plotting on the Cartesian coordinate plane, students develop a deeper understanding of what it actually means to plot the graph of a function.

The primary function when it comes to graphing calculators is the ability to input a function and have its graph appear in a manner of seconds. There are countless features available to analyze and manipulate the graph. The most commonly used are:

Graphing makes word problems make sense

Most application problems (you know, those dreaded word problems about trains, planes, projectiles, maximizing revenue, finding the normal force or coefficient of friction) in algebra classes can be more easily solved and understood when graphed. Graphing the equations you are trying to solve gives you a visual representation of the functions, and allows you to see what exactly it is you’re solving for. The majority of us are primarily visual learners, and a graphing calculator greatly adds to the learning process.

What to look for in a graphing calculator

It has to work for you. There are varying levels of power, sophistication and capabilities in graphing calculators, and it’s important to choose the one that’s right for you. For the high school student who just got comfortable using a regular scientific calculator last year, it is best to start with a more basic model, such as a TI-8or TI-8Both are quite user-friendly, with large easy-to-read buttons and excellent display of numbers, functions, and parentheses (or brackets).

Brief History of Graphing Calculators

The graphing calculator traces its roots back to as early as the 1600s. Over the centuries, calculators have transformed from a device that is solely used for scientific purposes to a household device that anyone can use. The earliest calculator models were expensive, not to mention bulky and cumbersome to use, a far cry from the affordable and lightweight devices that we see today.

Before the 1960s, mathematicians basically relied on the slide rule for their complex work. In 1985, Casio rocked the very foundations of the calculator industry when it launched the first graphing calculator model. Graphing calculators have since become faster and more convenient to use. The tasks that they can perform quickly also became more complex. In no time, these class of calculators became a fixture in workplaces and classrooms.

Standard Specifications

Most graphing calculator models run on batteries and come with at least 500 built-in functions, although some models can offer a lot more than that. Font size options are also usually available. Memory ranges from 24KB to more than 200 KB RAM; and some models are even upgradable.

Most graphing calculators today are equipped with the following:

Conventional Display – Also referred to as natural display, it shows mathematical expressions exactly the way they would appear when manually written.

USB Capabilities – This feature allows the graphing calculator to adapt to other devices. It also lets you maintain programs and updates.

3D Graphing Capabilities – 3D graphing offers a range of functions in the XYZ area. While some graphing calculators are only equipped with 2D capabilities, 3D is fast becoming the standard.

Other Things To Take Note Of

With the advancement in technology, the demand for more complex calculating devices has continued to rise. Thus, you need to carefully study the various features of the specific models you are considering to purchase. If you intend to use the calculator for your tests and other schoolwork, find out which types are allowed by your school. If you’re a professional, determine if the calculator has all the capabilities that you need for your tasks.

Regardless of the model you go with, you will enjoy the benefits of quickly solving math problems. It will help you shorten the time spent for completing specific tasks. If you need to upload additional programs and updates, make sure that the device has USB connectivity. While a standard model is generally durable, you may want to invest more for models of the highest quality to guarantee efficient use for a long time. These models may be a bit more expensive, but they offer more functions.

Speaking of durability, for students and people on the go, a good unit to have must be sturdy enough to withstand the abuse of being confined in a purse or backpack for entire school years.

Go for a graphing calculator that is ergonomically-designed, and equipped with a user-friendly and convenient-to-use button layout. The commonly-used functions must be easy to access. The math formulas must not be hidden under tons of lists and endless menus. You should be able to get the desired symbol or formula quickly and intuitively. Button markings must be easily readable, and the display should provide a high-contrast, clear readout. Following this guide is a review of some of the best graphing calculators that you can check out to help you make a sound buying decision.

HP G8X92AA LA Prime vGraphing Calculator

The G8X92AA from HP is a cutting-edge new generation statistical calculator that boasts of features like a full-color display, multi touch control options like the keyboard or the touch screen and the ability to switch between different types of views (Graphical or numbers) with dedicated keys.

That’s not all either. With a simple firmware upgrade and HP Prime Wireless Kitand HP Connectivity Kit, you also get support for P2P (Prime to Prime) and in-class Wi-Fi that allows you to wirelessly connect and transfer data between the calculator and a computer. As would be evident by now, the usage of the calculator is not limited to a statistic class. It is also widely used in engineering, chemistry, computer science, trigonometry and the likes.

Packed To The Brim With Features

The HP G8X92AA is hands down, the most feature rich statistic calculator that we have seen in recent times. There’s no end to what you can do with it. But just to give you an idea, it features graphing functions like scatter plot, 2-D, parametric and more, Scientific functions like unit conversions, Boolean graphics and angle conversions, statistical functions like Σx, Σx2, Σy, Σy2, Σxy, linear regression and more.


The most desirable ones have a full multi colored LCD display. But even black and white displays work equally well provided that the numbers are sharp and crisp. You will be using the calculator in differently lit rooms. So, the display is of penultimate importance.


Apart from the type of calculations that you can perform, there are many other features that can make life simpler while you are using the best statistical calculator. The playback feature or a rewind feature as it is called in some models, allows you to go back and alter a formula or a calculation. Advanced graphing will be immensely helpful in both statistical as well as scientific calculations.

An internal storage memory allows you to store your calculations for future reference. USB connectivity will let you transfer the data from the calculator to a computer and vice a versa. Some advanced calculator models even support Wi-Fi these days allowing you to wirelessly transmit data. When it comes to features, the sky is the limit. But an often overlooked one is a sliding protective cover that keeps the keypad safe from wear and tear due to repeated use.

It goes without saying that you wouldn’t want to spend a huge amount to get a decent statistical calculator. And to that end, we have picked some amazing budget priced models for you. But as they say, you get what you pay for. The tradeoff is that lower priced models will rarely be as feature rich as the regular priced ones.

TI-Nspire CX
