Numbers Plus
A good calculator should be only
the start for teaching math in elementary schools. Casio has a new package that
includes its fx-55Plus calculator that can handle natural input plus a set of
manipulative items and help kids learn math. In addition to the calculator, you
get a poster, teacher’s guide, emulation software for projecting the
calculator’s keys and display as well as a box of items to help teaching. It
costs $575 at EAI Education.
