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.
