1. Grade/Age Level
This lesson is for college Pre-Algebra students at a two-year community college. Many of
the students have recently graduated from high school. A few of the students are older and
are returning to school after an extended period of time.
2. Subject Area
This lesson is designed for Pre-Algebra students. Most of the students have been introduced
to the subject matter before. This lesson is specifically an introduction to the basics of
algebra and the vocabulary used in algebra.
3. Time Allotted
This lesson is meant to be done within one 60 minute class period.
4. Lesson Description
In this lesson, the students will be introduced to the vocabulary used in algebraic
expressions and equations. The students will also be taught about descending order for
algebraic expressions and how to put an algebraic expression in descending order.
5. Instructional Objectives
By the end of this lesson, students will be able to:
a. Define the different parts of an algebraic expression and label them
b. Express an understanding of descending order in algebraic expressions
c. Recognize when an algebraic expression is in descending order
d. Write algebraic expressions in descending order
6. Instructional Procedures
a. Lesson Set
Students will be given a worksheet with a list of terms and an algebraic expression. They
will be divided into groups of three or four students and as a group they will use the
terms on the worksheet to label the parts of the expressions. Students will be allowed
to use their textbook and the definitions graphics from this lesson as references.
b. Techniques and Activities
After each group has filled out the worksheet, each group will come up and label one
part of an expression that will be written on the whiteboard. As a class we will discuss
the terms on the worksheet, their meaning, and how they relate to algebraic
expressions. After the students show a clear understanding of the definitions, the class
will be introduced to descending order for algebraic expressions. As a class we will
discuss what descending and ascending mean and how to write expressions in this
order. Students will then be given a practice set of questions to work on labeling
expressions and writing them in descending order. Students won’t be required to do
these questions as a group, but they are welcome to work together if they wish. These
questions will be turned in and graded.
c. Lesson Closure
As a class, we will discuss any questions or concerns the students have about the lesson,
the definitions, and descending order. We will review any questions or problems the
students had with the practice problems.
9. Adaptations
When needed, adaptations will be made such as extended time, reading directions out
loud, and any other accommodations needed.
10. Supplemental Activities
Students needing extra help can receive one-on-one instruction from the instructor by
asking questions when working on the in class practice questions or meeting with the
instructor outside of class. Students can also receive additional help form the on campus
Math Lab.
11. Assessment/Evaluation
Students will be assessed on their participation in the group worksheet activity. The
worksheet will be graded on participation as well as accuracy of answers. Student
understanding will be informally assessed during the group discussions on the algebraic
terms and writing expressions in descending order. The practice questions will be
entered into the computer and graded electronically based on accuracy of the answers.
At the end of the unit, students will be a given a unit test.
12. Learner Products
Students will have filled out the group worksheet. They will also have completed the
practice problems for the lesson.
