Although curriculum and teaching method change slowly, we have witnessed some major changes in mathematics instruction over the last ten years, most notably the emphasis placed on the problem-solving process. We've also observed vast amount of resources funneled into microcomputer equipment for young students. In part because of this interest in microcomputer technology, we may have overlooked a technological device that has even more potential for revitalizing and enhancing mathematics instruction for children. Simple four-function calculators have been hoved to the back burner (or rear shelf of the school storeroom) in the past few years, but interest in them is reviving as evidenced by this focus issue.
