For nearly 20 years, graphing calculators have been a staple in mathematics classrooms, and the access to the technology has been expensive. Typical graphing calculators costs upwards of $70, and the most popular model of them all, the Texas Instrument TI-83, sells for over $100. This cost is prohibitive for many students, but there are very little alternatives. With the abundance of mobile technology offered today in the form of smartphones, tablets, and laptops, and their rising use in the classroom, are we not taking advantage of technology here?
I am here today to present to you the Desmos Calculator, a free graphing calculator software that will run off browsers on any modern mobile device. This tool has been invaluable to myself as an math teacher, but presents a valuable opportunity for investment. Coupled with a platform for classroom activities and its growing connections with textbook publishers, Desmos Inc. and its calculator is well positioned to become a leader in classroom graphing technology in the years to come.
Please explore my analysis of Desmos Inc. and its product, the Desmos graphing calculator, and learn my recommendations for the future of graphing technology in the classroom.
