Even the less expensive models of graphing calculator range from $25 and up. And if your young hooligan sees fit to lose his graphing calculator, as mine have done, there’s another big cash outlay to replace it.
Math teachers provide graphing calculators for their algebra, algebra II, trigonometry, calculus, probability and stats and geometry students. However those calculators are for use in the classroom only. The TI-83 graphing calculators are far too expensive to send home with students. If your student should be allowed to take his TI-83 graphing calculator, guard it as you would the crown jewels. It will cost about that to replace; trust me, I know of what I speak. And your student will need a graphing calculator for homework.
