NES Middle Grades Math: Transformations Chapter Objectives

There are four content domains in the NES Middle Grades Mathematics test; the lessons in this chapter will primarily respond to content in the Measurement and Geometry domain (which makes up 25% of the test). Objective 0009 is the related objective, which requires test-takers to demonstrate an understanding of transformational geometry. You must complete the 150 multiple-choice questions in the test within 4 hours and 15 minutes and achieve a score of 220 on a scale of 100-300.

Rotations in Math: Definition & Overview

1. 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.

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.

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

3. 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.

Reflecting Simple Shapes in a Mirror Line

4. Reflecting Simple Shapes in a Mirror Line

What is reflection? How can we reflect a shape over a line? You will learn about this as well as about the important properties of reflection as it relates to math!

What are 2D Shapes? - Definition & Examples

5. What are 2D Shapes? - Definition & Examples

In this lesson, you will find out how a flat piece of paper will help you determine what shapes are considered 2D. You will also learn the wide variety of 2D shapes you may encounter in life.

Identifying the Line of Symmetry: Definition & Examples

6. 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.

Graphing Translations & Finding a Set of Coordinates

7. Graphing Translations & Finding a Set of Coordinates

In this lesson, you're going to learn how to translate figures by counting boxes, find the coordinates of points, and learn how to translate a figure more quickly using simple math.

Rotating Shapes by Degrees, Center & Direction

8. Rotating Shapes by Degrees, Center & Direction

In this lesson, you're going to learn about the definition and basic concept of rotation as well as how to rotate any shape about the origin in a coordinate plane. Finish up the lesson, then test your understanding with a quiz!

How to Graph Reflections Across Axes, the Origin, and Line y=x

9. How to Graph Reflections Across Axes, the Origin, and Line y=x

A graph can be reflected in three ways - across the axes, the origin and the line y = x. There are specific rules to perform each reflection. This lesson will describe those rules and show you how to perform these reflections.

Distance Formulas: Calculations & Examples

10. Distance Formulas: Calculations & Examples

Let's go on a road trip! In this lesson, we'll practice calculations involving distance, rate and time. We'll also look at how we determine the relationship between distance and fuel.

Finding Distance with the Pythagorean Theorem

11. Finding Distance with the Pythagorean Theorem

How much faster is it to cut the corners in a race around the block? In this lesson, review the Pythagorean Theorem, and figure out how to solve without a right triangle.
