"An iPad is a pricey gadget but not necessarily an entirely extravagant purchase. The App Store offers much more than "Angry Birds" and Instagram. Its stock includes educational tools for just about every high school subject and standardized exam. By providing access to no- and low-cost alternatives to other academic expenses such as graphing calculators, textbooks and tutors, iPads have the potential to save families money. At their best, educational apps empower students to customize their study methods so that every learning style has a path to academic achievement"
