# Ch 18: NES Middle Grades Math: Number Patterns & Sequences

### About This Chapter

## NES Middle Grades Math - Number Patterns and Sequences - Chapter Summary

If you're going to take the NES Middle Grades Math examination for teacher certification soon, you'll want to brush up on number patterns and sequences. This chapter allows you to take another look at the patterns of arithmetic and geometric sequences and explores the terms that make up sequences. It also highlights the standard formulas of arithmetic and geometric sequences, and it likens these sequences to real-life scenarios. Review the videos so that you may:

- Describe the basics of mathematical sequences
- Classify arithmetic and geometric sequences
- Learn more about linear relationships and common differences in arithmetic sequences
- Evaluate variable expressions for arithmetic sequences

Each of the entertaining, self-paced videos tackle one of these subjects and dissects them. Increase your knowledge of number patterns and sequences so that you can perform better when answering related questions on the NES Middle Grades Math examination. Pause and rewind the online videos, and focus on the areas you need to revisit. It's recommended that you take the self-assessment quizzes and the practice chapter examination. You could even re-take the quizzes and print out the results, which can be studied frequently and conveniently.

### NES Middle Grades Math: Number Patterns and Sequences Chapter Objectives

When you sit for the NES Middle Grades Math examination, you should be prepared to finish four content domains in four hours and 15 minutes. The *Number Sense and Operations,* *Algebra and Functions,* *Measurement and Geometry* and *Statistics, Probability and Discrete Mathematics* content domains account for 17%, 33%, 25% and 25% of the examination score, respectively. Apply what you discovered and recalled during this chapter when addressing pertinent questions on the computer-based assessment. In all, there are 150 multiple-choice questions on the exam.

### 1. What is a Mathematical Sequence?

Math is often the most fun when it acts like a puzzle to be solved. The branch of math where this is the most true involves sequences. Get an introduction to the basics and important vocabulary, as well as learn where sequences appear in nature!

### 2. How to Find and Classify an Arithmetic Sequence

Arithmetic sequences are everywhere, and with a few tricks you learn here, you could end up looking like a psychic the next time you go to a movie or a football game!

### 3. Finding and Classifying Geometric Sequences

Want your YouTube video to get a lot of hits? Besides including a cute baby or an adorable cat, getting your video to have a big common ratio is the key. Learn what I'm talking about here!

### 4. How to Evaluate & Write Variable Expressions for Arithmetic Sequences

Being able to figure out sequences as well as describe them are some of the most important skills in math. In this lesson, we learn how to evaluate and write arithmetic sequences and geometric sequences.
