Students explore problem situations involving linear relationships. The idea of packaging is used to introduce students to the concepts of surface area and volume. By measuring, filling, and designing packages, students develop formulas for volumes and surface areas of prisms, cylinders, cones, and spheres. By playing and analyzing computer and carnival games, students investigate ideas about probability. As students work with news reports about natural disasters and accidents, they develop methods for making sense of large numbers.
Students learn to use graph and equation models to represent data trends.
Students study exponential growth and decay through tables, graphs, and equations. A real-world exploration of quadratic relationships using table, graphs, and equations. Students investigate factored and expanded forms of quadratic expressions, and learn about parabolas. As Students build on their earlier work with solving linear equations, and solve simple quadratic equations. Familiar items help students understand symmetry and transformational geometry.
