The Role of Manipulatives in Arithmetic and Geometry Tasks

Research in the area of arithmetic supports PDL, but it has not been examined in geometry. This paper examines the possibility that physical action may have different effects in arithmetic and geometry tasks in the context of two studies with kindergarten, first- and second-grade students. In the arithmetic study, students solved addition word problems using manipulatives and drawings. In the geometry study, students completed a shape identification task with manipulatives and drawings.
