By the end of this lesson, you should understand that: ◦ Addition and subtraction are inverse operations ◦ Multiplication and division are inverse operations ◦ Solving for a variable includes isolating it by “undoing” the actions to it
3
By the end of this lesson, you should be able to: ◦ Solve for a variable in a linear equation ◦ Explicitly write out the order of operations to evaluate a given expression
4
Main idea: ◦ Solving equations is based on the principle of undoing operations (and steps) and balancing each operation
5
By the end of this lesson, you should understand: ◦ Proportional relationships are based on a constant ratio ◦ Rules for solving equations can be applied in unfamiliar situations
6
By the end of this lesson, you should be able to: ◦ Set up a proportion based on a contextual situation ◦ Solve a proportion using algebraic methods
7
Main idea: ◦ Proportionality preserves the ratio between values Main idea: ◦ Mathematical rules are consistent: foundational rules for solving equations can be used on any equation
