  • I prefer email to communicate simply because the ease of responding, but I can always call if requested. Please do not hesitate to contact me if you have any questions or concerns.

Materials Needed

  • Algebra 1: minimum THREE subject notebook and folder or binder with plenty of paper, pencils, colored pencils or pens would be helpful

    Honors Pre-Calculus: minimum THREE subject notebook and folder or binder with plenty of paper,  pencils, colored pencils, pens or highlighters would be helpful, 

    I suggest that you have at least a scientific calculator at home to use, while not required if you would like to purchase a graphing calculator please purchase a TI-84.

    If you must use your phone at home, Android users can download a free app called "Wabbitemu" which is a graphing calculator emulator and I can help you set it up. iOs users please DO NOT use your phone calculator, it is not the greatest. With either phone you can use desmos scientific calculator which is prefered.
