Intensive quantity is an important concept in the area of natural science and it is said that difficulties in understanding the concept result in problems in grasping the laws of nature. As has been the case previously, deaf children continue to show no academic improvement with arithmetic and mathematics. With the objective of coming up with instruction methods to remedy this current situation, the subject of intensive quantities is considered to be an unavoidable subject that requires investigation. Therefore, this report attempted to analyze research trends relating to intensive quantities and peripheral areas by research conducted for the hearing children. As a result, it was discovered that: 1) With instruction on intensive quantities, concepts regarding “averages” and “uniformity” are important, while with instruction of percentages, “ratio invariance” and “ratio constancy” concepts are critical; 2) The difficulties with instruction on intensive quantities lay in “understanding equivalence”; 3) The difficulties with instruction on percentages lay in “corresponding expressions for two amounts.”
