Most parents would never doubt an item on their child's back to school list, but that sometimes changes when they need to buy a graphing calculator. These calculators can be pricey and parents usually want to know why they are necessary. Rest assured, although they may cost more than the average calculator, they are an important tool for any student.
The main reason that teachers require their students to have graphing calculators is that they are necessary in certain subjects. When a student begins studying higher level algebra or trigonometry, they will need to solve problems that they simply can not do on their own. In these courses, a student can not be successful unless they have a graphing calculator.
They are also very helpful in keeping students organized through the semester. A graphing calculator with adequate storage can store class notes as well as equations and lines. This makes it much easier for a student to complete their work because they do not need to enter information into the calculator multiple times in order to check their work or complete a program.
It is also important for parents to remember that their child may use the graphing calculator in a variety of classes. Aside from math class, they are often a requirement for students who are studying chemistry or physics. If a student plans on pursuing math at the college level, the calculator is a good investment in their academic future.
A graphing calculator may be the most expensive school supply a parent ever needs to supply, but it is necessary for their child's success. In many math classes, students simply will not be able to do the work if they do not have one. In addition, they include on board storage that helps students stay organized and efficient in their problem solving.
