Educ. 51, No. 3, 197-210 (2012).} \itemab Summary: We will develop and implement the teaching program of functions, on the subject of ``poster-making utilizing the graph art" in the math camp for middle-school students. And we will examine the didactical significance through student's activities and products. The teaching program of functions utilizing the graph art can be promoted self-directly the understanding of the function concept and the ability for handling functions. In the process of drawing up the graph art, in particular, this program help students to promote the ability for problem-solving and mathematical thinking, and to communicate mathematically and attain the his own level. Ultimately, this program have a positive influence upon cognitive and affective and areas with regard to mathematics. \itemrv{~} \itemcc{U73 I20 D40} \itemut{the teaching of functions; graphic calculators; graph art} \itemli{} \end
