Math Department Teachers
  • Graphing Calculators

    Some parents and student may be interested in purchasing a Graphing Calculator to be used while in classes at Parkway Central.  This would then be a benefit on the ACT as well as on future AP math tests.  However purchasing a graphing calculator is not a requirement for any course.  IF you plan to purchase a graphing calculator, then please consider purcahsing the TI-84 or TI-84 Plus calculators.  This is the only graphing calculator that Parkway Central teachers use besides the free online DESMOS calculator.  If you have any questions, please email the department chair, Mr. Lehmann.
