# Ch 10: Common Core HS Algebra: Sequences and Series

Find lessons for high school algebra. These lessons meet the Common Core Mathematics standard for sequences and series (CCSS.Math.Content.HSA-SSE.B.4).

Standard: Derive the formula for the sum of a finite geometric series (when the common ratio is not 1), and use the formula to solve problems. (CCSS.Math.Content.HSA-SSE.B.4)

Students who have mastered this standard are able to explain the importance of number patterns in mathematics. When working with sequences, they will be able to discern and explain the difference between the different types of sequences and series.

Lessons in this standard cover concepts such as:

• Finding and classifying arithmetic and geometric sequences
• Calculating arithmetic and geometric series
• Working with summation notation and mathematic series

Students demonstrate this standard when working with any set of numbers while attempting to find a pattern. An example of when mastery of this standard helps students is when they need to calculate mortgage payments.

### How to Use These Lessons in Your Classroom

Here are some tips for how to use the lessons to support instruction in this standard:

#### Sequence Classification Lessons

Develop a worksheet that includes arithmetic and geometric sequences. Exhibit the video lessons 'How to Find and Classify an Arithmetic Sequence' and 'Finding and Classifying Geometric Sequences.' Pass out the worksheet to your students for homework. Spend the next day going over the correct answers and explain how each sequence is classified.

#### Summation Notation and Mathematical Series Lessons

Display the video lesson 'Summation Notation and Mathematical Series.' Give the students time to take our video lesson's supplementary quiz. After discussing each student's quiz score, take time to retake the quiz as a class while explaining how to find each answer.

#### Geometric and Arithmetic Series Calculation Lessons

In class, show the students the video lessons 'How to Calculate an Arithmetic Series' and 'How to Calculate a Geometric Series.' Assign the video lesson 'Arithmetic and Geometric Series: Practice Problems' for homework. During the next class, go over the assigned homework and have the class take the quizzes that we provide for each lesson.
