NCTM's "Technology Principle" challenges mathematics teachers to rethink the mathematics they teach, investigate technological tools for learning mathematics, and consider how they can support students in learning mathematics with technology as a tool. In concert with the NCTM's emphasis on using technology as a tool in mathematics, ISTE's NETS for Students identifies the importance of students learning to use technology as productivity, communication, research, problem-solving, and decision-making tools. This challenge, however, carries with it the requirement that students learn the basic operations and concepts of technology. Thus, more and more, mathematics teachers must redesign their curriculum and instruction to help students learn about the technology they will use to learn mathematics. A spreadsheet is one of these tools. Math teachers are challenged to think about scaffolding students learning about spreadsheets while they are also learning mathematics. This learning can begin at least by middle school (if not earlier).
