Lesson Summary:

In this lesson, the Distributive Property is used to simplify expressions and word phrases are written as algebraic expressions. By identifying like terms and distributing values, students learn to simplify expressions such as 5 times the sum of 4 times the number and 1. Additionally, the lesson covers how to write expressions from word phrases, such as 3 less than twice the difference of a number and 5. Through these techniques, students develop foundational skills that will be built upon in future algebra lessons.
