The Verb Recognize a verb when you see one. Verbs are a necessary component of all sentences. Verbs have two important functions: Some verbs put stalled subjects into motion while other verbs help to clarify the subjects in meaningful ways.

I ask what the variable stands for, what the coefficient is, and what it means. I ask how they used the expression to find how fast Luis was driving.

I want my students to follow the order of operations when simplifying expressions. Because this lesson combines all of the skills learned so far in this lesson, there is not an introduction to new material section.

The first example is a verbal expression that students translate and then evaluate for a given value. The process students should use to write and evaluate the expression can be seen and heard here.

The second problem presents students with a real-world example. Students must define the variable before writing and evaluating the expression. As students work, I circulate around the room.

I am looking for: Are students correctly identifying the variable? Are students correctly identifying the constant? Are students correctly identifying the coefficient? Are students correctly translating the verbal expression into an algebraic expression?

Are students using substitution and their expression correctly to solve the problem? How did you know what the variable was? How did you know what the constant was? How did you know what the coefficient was? How did you know what operations to use? How did you know the value of the variable?

Why does the expression you wrote help you solve the problem? Use the steps above as questions if more are needed. After 10 minutes of partner work time, I bring the class back together for a discussion. I use Problem 2 to drive our conversation. I pull a popscicle stick to cold call on a student for work to display on the document camera.

The class gives positive and critical feedback on the displayed work. Students complete the Check for Understanding independently. Partner Practice and CFU. The first four problems require students to evaluate when n is a decimal. As I am circulating, I am checking to be sure that students are careful with their arithmetic when they are evaluating.

Throughout this section, I am praising students for their organization. Students must annotate the problems, define their variables, and keep their work space neat and orderly. Problem 8 can be difficult for students, in that students have to find half of a quantity.

I display work for Problem 7. I intentionally display the incorrect expression, using 4 - 2c. I have students turn and talk about my expression. Finally, I ask for a student volunteer to share out the correct expression.The Verb Recognize a verb when you see one.
