As students prepare for a new school year, the standard math toolkit is changing. Handheld calculators, long a mandatory and expensive purchase for algebra and calculus classes, now share space with free digital graphing software. This shift changes how schools teach mathematics and how students take standardized exams.
What Happened
Texas Instruments calculators have dominated classrooms for decades, but free, browser-based alternatives like Desmos are becoming the new standard. School districts across the country are redesigning their math curriculum around these web-based tools. For instance, the Newton Public Schools Math Curriculum Committee recently adopted the Amplify Desmos Math curriculum for grades K-5 because teachers favored its interactive features. This transition is backed by a network of Amplify Classroom Fellows who help integrate these digital tools into daily lessons.
The Bigger Picture
This shift to digital math tools coincides with changes in standardized testing. On the digital SAT, students no longer have a no-calculator section. A calculator is permitted throughout the entire math portion, according to the College Board SAT testing rules. Students do not even need to bring a physical device. A built-in Desmos graphing calculator is now embedded directly inside the College Board Bluebook testing app. Still, physical calculators remain popular. Many students bring a physical Texas Instruments TI-84 to avoid testing anxiety and have a reliable tactile backup. This testing change comes alongside other shifts in admissions, such as Texas public colleges accepting Classic Learning Test scores as an alternative to traditional exams.
What This Means for Families
Parents often worry that lacking the latest hardware puts their children at a disadvantage, but research suggests otherwise. A decade-long study by the Cato Institute on the One Laptop per Child program in public schools found that distributing personal laptops had no long-term impact on test scores, graduation rates, or university enrollment. In fact, rapid digital transitions can complicate schoolwork for families facing housing or financial instability, as documented in digital learning initiatives like the Manaiakalani research project. Because tools like Desmos are free and run on almost any web-connected device, they remove the need for expensive hardware.
What You Can Do
- Have your student practice using the built-in Desmos tool within the Bluebook app before test day.
- Check your school's curriculum requirements. Some classrooms still require a physical, offline calculator like a TI-84 for in-class exams where internet access is blocked.
- Focus on math comprehension instead of buying expensive hardware. These digital tools are free on home computers and tablets.
