Math Aids

Math aids are probably the most "mainstream" low-tech devices. Everyone uses calculators! The advantages of such aids are obvious:

• Math devices speed up calculation time and generally improve accuracy.
• Use of a calculator can be a "first step" into the use of keyboards and electronic technology.
• Providing alternate ways to "write" numbers offers students the option to work more independently.
