Subject: Re: Integer Chips

	Using plastic "tile spacers" bought at a harware store come in the
shape of a +. Negative is created by trimming two arms off the +. They
carry the immediately obvious idea of neutralization by combining
opposites. They are also easy to draw a picture of as the students
move from modeling to recording then to numbers. Bingo chips, etc. are
a cute, but meaningless and distracting activity that won't naturally
become a written expression.
