Lesson Summary:

In this lesson, students learn how to use the distributive property to simplify expressions. The teacher works through several problems, showing step by step how to distribute the term outside the parentheses to each term inside, and then simplify the expression using combining like terms. Students also learn how to rewrite an expression with a minus sign outside the parentheses as the opposite of everything inside the parentheses, and how to deal with negative and positive numbers.
