Big Calculator: How Texas Instruments Monopolized Math Class
These $100 calculators have been required in classrooms for more than 20 years, as students and teachers still struggle to afford them
This fall, Stephen Thompson began his first year of teaching Algebra 2 and college prep classes to 11th and 12th graders at a public high school in northwest Baltimore. On top of the typical stress of any first-year teaching experience, Thompson realized that along with other out-of-pocket classroom expenses, he would have to buy a pricey piece of classroom equipment: graphing calculators.
