Math Classroom Supplies

All math classes (except Calculus) - The recommended calculator is a TI 30X IIS
 
 
Calculus - You must have a graphing calculator.  The recommended model is a TI 84 plus
 
 
Geometry - You will need a protractor and a compass.  Any protractor will do fine, but many compasses are poorly made and make it difficult to use.  I recommend choosing one that has a turning gear used to increase or decrease the size of the circle's radius.  Here is a link for one that I have used.
