Calculators
After solving math problems, kids can use calculators to check answers. Calculators also can help compute complex mathematical functions. Office supply sections of local drug and grocery stores, as well as local and online office supply, electronic, and computer stores sell standard calculators.
Talking Calculators
Kids who struggle with math often benefit from the use of calculators that provide auditory, as well as visual, feedback. Talking calculators use a built-in speech synthesizer to say numbers, symbols, or operation keys as they're pressed. They also read back answers from completed problems.
Hearing the numbers or symbols helps some kids find errors they made when pressing keys. Hearing the answer helps you double check for errors made when copying numbers, such as writing "91" for "19" or confusing "6" with "9."
Talking calculators vary in size, shape, color, and functions. Some models have an earphone jack. The external speaker automatically shuts off when the earphone is inserted, so the calculator can be used without disturbing anyone.
