Choosing a Calculator

In the classroom

One question I get all the time is “what calculator should I buy my student?” I always suggest that students use the same calculator at home that their teacher uses in class. By “same” I mean same manufacturer and same model, the color of the outside of the calculator doesn’t matter. Also check what type of calculator will be allowed on tests. 

For 6th grade to Algebra I students

I suggest the TI-30X, which is a basic scientific calculator that you can get from places like OfficeMax and Walgreens. They are also available on Amazon here. I suggest any Texas Instruments brand scientific calculator that has at least 2 lines of text (so you can see what you typed in). These are usually less than $15. This calculator is also useful for physics and advance calculus classes that restrict calculators on tests.   

For Algebra II students to Calculus students

 Most public high schools traditionally use the TI-84 plus calculator starting in Algebra II. The only change in the TI-84 plus in the past years have been different colors (silver, pink, etc) and different batteries. They all should function the same. I get my calculators from eBay, since I can buy a calculator for around $50 used when it is normally $110 new. When purchasing a calculator on eBay, I suggest that you check that it comes with a cover, is from a highly rated company, and has at least a 30 day warranty. Here is the Amazon link for the TI-84 plus. Students can use this calculator on the SAT, so it’s good to know how to use it now.    


Most private high schools use the TI-Nspire. This is also allowed on the SAT, and can be found for cheaper on eBay. When buying this calculator on eBay, also check that it comes with the power cable.     

Getting the most out of your calculator

Using the same calculator on homework will help you prepare for the test. Our tutors can help students ensure they know all the great functions of their specific calculator.

Avoiding Silly Math Mistakes on the SAT

The SAT is stressful enough, try these tools to avoid silly math mistakes on the SAT and get the most points you can. 


It's better to spend a couple extra seconds on a problem and get it right than race though all the problems and get most of them incorrect.
