Abstract

This study reports a part of a full study on how to support students understanding of area measurement. Six grade 7 students participated a preliminary teaching in the first cycle. We designed instructional sequence activities consisting of reallotment and tiling activities in six meetings. Reallotment activities embed the concept of conservation of area. Meanwhile, the tiling activities embed the square unit of measurement. Comparing areas of leaves and rice fields, reshaping are activities using reallotment activities. Comparing areas of tiled floors are activities using square unit of measurement. The result indicated that in comparing areas, students could develop their understanding of conservation of area by overlapping, cutting, and pasting. Students could reshape quadrilaterals into a rectangle. In reshaping, students understood that an area of a figure will not change when it is reshaped. Therefore, students applied area formula of rectangle and derived the area formulas of quadrilaterals and triangles
