Ch 20: Transformations: NBPTS Math - Adolescence & Young Adult

About This Chapter

Let us help you in your preparation for taking the National Board for Professional Teaching Standards (NBPTS) Math certification exam. The lessons in this chapter cover transformations.

Transformations: NBPTS Math - Adolescence & Young Adult - Chapter Summary

These lessons are mostly short videos that will help you in answering questions on the NBPTS Math test about transformations. When you finish this chapter, you will have gained knowledge about lesson topics like:

  • The definition of and terms used with translation in math
  • Reflections in math, including glide reflection
  • How to identify the line of symmetry
  • Rotations and the use of rotational symmetry
  • How to apply dilation in math

This series of lessons uses of brief videos to present the majority of the subject matter. A quiz after each lesson provides an opportunity for self-assessment. If you need to review any of the information, you can look over the written transcript or use the video timeline tool to go right to any section you want to replay. You can also ask the instructor a question using the personal dashboard feature.

What is Translation in Math? - Definition, Examples, & Terms

1. What is Translation in Math? - Definition, Examples, & Terms

In mathematics, translation refers to moving an object without changing it in any other way. This lesson will describe how to translate an object and give some examples. A quiz will follow to test your knowledge.

Reflections in Math: Definition & Overview

2. Reflections in Math: Definition & Overview

A reflection of an object is a 'flip' of that object across a line. This lesson will describe the basics of reflection, how to recognize one and how to create one.

Glide Reflection in Geometry: Definition & Example

3. Glide Reflection in Geometry: Definition & Example

In this lesson, we will look at transformations of geometric figures and concentrate on one type of transformation in particular: a glide reflection. Through a definition and examples, we will become comfortable with this type of transformation.

Identifying the Line of Symmetry: Definition & Examples

4. Identifying the Line of Symmetry: Definition & Examples

Symmetry can occur in many different ways in mathematics. In this lesson, learn how to identify unique forms of symmetry by finding the line of symmetry.

Rotations in Math: Definition & Overview

5. Rotations in Math: Definition & Overview

A geometric rotation refers to the rotating of a figure around a center of rotation. This lesson will get you going on rotations, give you some examples, and end with a quiz that tests your knowledge of rotations.

What is Rotational Symmetry? - Definition & Examples

6. What is Rotational Symmetry? - Definition & Examples

If you have ever tried to hang a picture and not been able to tell which end was up, then your picture might have had rotational symmetry. Rotational symmetry is the characteristic that makes an object look the same even after you've rotated it.

Dilation in Math: Definition & Meaning

7. Dilation in Math: Definition & Meaning

Dilations are transformations that change figures in specific ways. Learn about these changes and how to complete dilations here. Then test your understanding with a quiz.
