Dissecting a Square SS3

In this resource from the DfE Standards Unit, students learn to express a part or whole diagram in fractions or percentages, convert a fraction to a percentage (using a calculator), calculate areas of rectangles, triangles, circles and parts of circles and add, subtract and multiply fractions. This session builds on students’ prior knowledge about fractions and
percentages and finding areas of rectangles, triangles and circles. Students begin by completing a short discussion task that is designed to reveal their existing understandings and misunderstandings about fractions. (Grades D-F)
