Abstract
This paper investigates Grades 4,6 and 8 students' confusion between area and perimeter. Students were given area judgment tasks involving rectangles and their responses analysed in terms of the operations used and the strategies exhibited. Students were found to use both additive (Perimeter) and multiplicative (Area) judgment rules, and 7 different strategies. Those using an additive judgment rule tended to rely on rulers or fingers for measuring length and to align the rectangles vertically, whilst those using a multiplicative judgment rule tended to use overlay and partitioning strategies.
