This week students use their knowledge of simplifying expressions, order of operations and properties of equality to calculate the solution of multi-step equations. Students will use tables to determine their answer and check to determine if their solution makes the equation true. Monday homework...Inequalities in the Real World
Tuesday - 4H - no math homework - study for CANADA TEST Wednesday - Classwork and Homework
Thursday - Students calculate missing angle measures by writing and solving equations.
Friday - (Part 1 of lesson - we will finish early next week) Students will identify independent and dependent variables and use them to write algebraic expressions for rel world-scenarios. The big ideas for this lesson are that many real-world scenarios involve 2 things changing—called VARIABLES—and that independent variables cause the change for dependent variables. We can develop a way to discern which is which by using “Does ______ depend on _________, or does ___________ depend on ____________ (the other way around)?” statements. This will help students understand the relationship between the variables. During the lesson, students will be guided through the process of identifying variables, making “ _____ depends on ______” statements to match scenarios, labeling independent and dependent variables, and last, writing a simple “rule” or expression to match the scenarios. This will create a strong foundation for graphing these relationships in future lessons/standards, and for using the expressions to substitute and solve real-life problems based on such scenarios. Vocabulary Variable: (prerequisite from earlier lessons) a letter or symbol that represents an unknown number. Independent Variable: the variable that is causing the change; sometimes called the “input”. Dependent Variable: the variable that is being changed by the independent variable; sometimes called the “output”. This variable DEPENDS ON the independent variable!
