This study examined the effect of teaching a relation figure and a line figure on 5^<th> graders' solving proportion problems. Thirty three students were taught how to draw a relation figure and a line figure from word problems and how to make word problems from those figures in the unit of "proportion". All lessons were planned based on a mathematics lesson with a scaffolding, therefore, the important contents were taught repeatedly every lesson. The results of a post-test showed that their performance was better than the results of some national tests; they also created various word proportion problems from a relation figure and a line figure.
