Calculators
High school is where calculator needs split. Grade 9 and 10 math usually works fine with a scientific calculator. Senior courses in functions, calculus, and physics often require graphing.
The right sequence is to start with a solid scientific calculator and add a graphing model when the course actually requires it. That keeps costs down and avoids carrying an expensive device before it is needed.
