StatisticsStudents focus on using random sampling to draw informal inferences about a population. They investigate sampling from a population. They learn to estimate a population mean using numerical data from a random sample. They also learn how to estimate a population proportion using categorical data from a random sample. Students learn to compare two populations with similar variability. They learn to consider sampling variability when deciding if there is evidence that the means of two populations are actually different.
Functions in GeometryStudents learn the concept and definition of a function. A function is defined as an assignment to each input, exactly one output. Students relate a function to an inputoutput machine. Our work has relied on assumptions of constant rates, but now, students are given data that shows that objects do not always travel at a constant speed. Students learn that the assignment of many functions can be described by a mathematical rule or formula. Students understand the difference between functions of discrete and continuous rates.
They compare two functions represented in different ways. Students are presented with the graph of a function, a table of values, or an equation, and are then asked to determine which function has the greater rate of change. Students apply their knowledge of volume from previous grade levels to the learning of the volume formulas for cones, cylinders, and spheres. Students compare the volume of a sphere to cylinders and cones. Students extend what they learned about how to solve realworld and mathematical problems related to volume from simple solids to include problems that require the formulas for cones, cylinders, and spheres. Linear EquationsStudents extend what they already know about unit rates and proportional relationships to linear equations and their graphs. Students understand the connections between proportional relationships, graphs of lines, and linear equations. Students learn to write, simplify, and solve equations in one variable and then in two variables. Students learn that not every linear equation has a solution.
Students make connections between graphs, equations, charts, and ordered pairs and are able to calculate slope and intercepts from each of them. Students graph simultaneous linear equations to find the point of intersection and then verify that the point of intersection is in fact a solution to each equation in the system.
