Reflection Over The X and Y Axis: The Complete Guide

What is a Reflection in Math?

Image Source: Mashup Math FP

Learning how to perform a reflection of a point, a line, or a figure across the x axis or across the y axis is an important skill that every geometry math student must learn.

In real life, we think of a reflection as a mirror image, like when we look at own reflection in the mirror.

This idea of reflection correlating with a mirror image is similar in math.

This complete guide to reflecting over the x axis and reflecting over the y axis will provide a step-by-step tutorial on how to perform these translations.

 First, let’s start with a reflection geometry definition:

Math Definition: Reflection Over the X Axis

A reflection of a point, a line, or a figure in the X axis involved reflecting the image over the x axis to create a mirror image. In this case, the x axis would be called the axis of reflection.

Math Definition: Reflection Over the Y Axis

A reflection of a point, a line, or a figure in the Y axis involved reflecting the image over the Y axis to create a mirror image. In this case, the Y axis would be called the axis of reflection.

What is the rule for a reflection across the X axis?

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.

For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P’, the coordinates of P’ are (5,-4). Notice that the x-coordinate for both points did not change, but the value of the y-coordinate changed from 4 to -4.

What is the rule for a reflection across the Y axis?

The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same.

For example, when point P with coordinates (5,4) is reflecting across the Y axis and mapped onto point P’, the coordinates of P’ are (-5,4). Notice that the y-coordinate for both points did not change, but the value of the x-coordinate changed from 5 to -5.

You can think of reflections as a flip over a designated line of reflection. You can often visualize what a reflection over the x axis or a reflection over the y axis may look like before you ever apply any rules of plot any points. This aspect of reflections is helpful because you can often tell if your transformation is correct based on how it looks. If the new image resembles a mirror image of the original, you’re in good shape! If it does not, you probably did something wrong.

Examples of Reflection Over the X Axis and Y Axis:

Notice how the reflection rules for reflecting across the x axis and across the y axis are applied in each example.

10 Awesome End of Year Math Activities for Grades 1-8

Looking for Effective and Easy End of Year Math Activities?

The final weeks of the school year have arrived and keeping your students engaged in learning math is no easy task.

You can mix up your instruction and keep your students interested in learning math by incorporating a few awesome end of year math activities and projects into your upcoming lesson plans.

The following end of year math activity ideas are perfect for implementing during the final weeks of the school year, an extremely hectic time when sticking to your usual routine is nearly impossible.

And each end of year math activity is easy to modify to best meet the needs of your students! The activities can be modified for students at the elementary, middle, and high school levels.

So, which end of year math activity will you share with your students this spring?

(Tags: end of year math projects, end of year math activities, 1st grade, 2nd grade, 3rd grade, 4th grade, 5th grade, 6th grade, 7th grade, 8th grade, grade 1, grade 2, grade 3, grade 4, grade 5, grade 6, grade 7, grade 8)

1.) Math Book Report

Description: Standard math curriculums hardly ever make time for students to actually read about math. The end of the school year is the perfect time to give your students an opportunity to choose a book about math and create and share a book report.

One option is to have your students research a famous mathematician. I also like having students choose a math-related fiction book, like any of the ones included on this list of 13 STEM Fiction Books Your Kids Will Love.

3.) Barbie Bungee

Description: The Barbie Bungee data collection activity may be the most underrated math activity ever. Ideal for pre-algebra students, this activity gives students a fun and engaging opportunity to make predictions, collect real-world data, and then analyze the results within the context of their initial hypothesis. This activity is even endorsed by the National Council of Teachers of Mathematics (NCTM), who share free lesson resources for any teacher interested in trying the Barbie Bungee in their classroom.

4.) Escape Room!

Description: Classroom ‘escape room’ lessons are growing in popularity. Why? Because classroom escape rooms boost student excitement and engagement while helping your kids apply and improve their mathematical problem-solving skills.

If you are new to the idea of classroom escape rooms (sometimes called breakout challenges), check out this blog post So You Want to Build a Classroom Escape Room… by We Are Teachers.

5 Effective Strategies for Improving Your Math Warm Up Activities

Are your daily math warm up activities engaging enough to truly capture your students’ focus?

The most effective lesson-opening activities (engagement hook, anticipatory set, warm-up, etc) do two things: assess your students’ prior knowledge and build anticipation for the lesson ahead.

Achieving this goal requires a solid mix of fun and engaging strategies and activity ideas (and rarely relying on assigning routine practice problems).

For some awesome tips and activity ideas for how to improve your warm up activities and make the most of the first five minutes of your lessons, check out my brand new list of effective strategies:

---

1.) Show a Video Clip

Some math concepts are meant to be seen, and sometimes your students will need visual aids to help grasp complex mathematical ideas. By starting class with a short video clip, you are engaging your students’ ability to think about math visually—a mindset which will sustain throughout the remainder of the lesson, to everyone’s benefit.

Try It! Try using the video clip of Unit Rates in the Real-World below prior to teaching a lesson on solving word problems involving unit rates.

2.) Puzzles and Challenges

Engaging math challenges and puzzles are a great tool for giving your kids opportunities to have fun while problem solving and thinking mathematically at the same time, especially if you want to prevent them from growing bored of routine practice problems.

Try It! Try sharing this fun math puzzle with your kids at the start of your next lesson and watch your students’ engagement and interest skyrocket!

3.) Which One Doesn’t Belong? (WODB)

Instead of working on practice problems during a lesson's warm-up, students will be shown 4 somewhat related images and have to apply their reasoning skills to decide which of the images does not belong.

And here’s the catch….WODB activities do not have a single correct answer. The activity is designed to be interpreted in a variety of different ways in order to spark deep mathematical thinking and discussion (in small groups, whole class, or both).

4.) Think-Notice-Wonder (Writing Prompt)

Writing about math encourages creativity, exploration, and communicating one's thoughts and feelings, which leads to deep and meaningful understanding of difficult math concepts.

Think/Notice/Wonder is a great strategy for getting your kids engaged in math writing every day.
