Abstract
In this first year of a three-year study, we report on the abilities of groups of students from years 7-10 to generalise numerical operational strategies involving compensation adjustments in the four arithmetic operations. The Year 7 students, who had all participated in the Numeracy Project, were more successful than those in other year groups in using literal symbols to express generalities. The Year 9 students, about half of whom with Numeracy Project experience, were the least successful despite exposure to formal algebra.
