A Fifth Grader's Attempt To Expand Her Ratio and Proportion Concepts.
Lo, Jane-Jane; Watanabe, Tad
One fifth grade student, Martha, was encouraged to develop her informal ratio and proportion strategies during a 6-month teaching experiment. The challenges Martha faced during the teaching experiment are described. The current study supports the claim made by Kaput and West (1994) that initial instruction on ratio and proportion based on children's informal strategies should be introduced as early as the third grade. Contains 11 references. (Author/MKR)
