Geometry Vocabulary 8th Grade

[Beronike Watkin]

Thesegeometry vocabulary cards were creating using the CCSS. All geometry words covered in the standards are included in these matching cards. There is a picture, word and definition card for each one.

It is nearly impossible for students to learn all the geometry vocabulary terms they need to know during your geometry unit. Ideally, work on vocabulary throughout your entire school year to build a foundation. Already in the thick of your unit? No worries, just jump in now and continue your weekly routine through the end of the year.

Introduce a new word each week. When you have gone through all of the words students need to learn for your grade level, rotate through them again. Post the word with an illustration and a definition each week.

The next day, give another student a 35 card with the same vocabulary term and ask them to label something else in the room. You could have students label things in other parts of the school as well. Your students will suddenly be looking everywhere for objects that illustrate your geometry vocabulary term of the week, so that they are ready if you choose them the next morning.

Geometric art is so much fun to create and helps students think about and apply key geometry vocabulary. Here is a simple activity that makes a perfect math station. All you need is paper, rulers, dice and markers, crayons or colored pencils.

Students can roll the dice as many times as they like to build their art piece. I recommend around 10 rolls. When they are finished they can color in the piece to complete it. These geometry art creations make a great bulletin board display after they are finished!

Give them a list at the start of the day using rooms they will visit that day in their regular schedule. I.e. Find an obtuse angle in the cafeteria, find a pentagon in the library, find parallel lines on the playground, find perpendicular lines in the hallway.

Bonus points if an administrator is walking by and overhearing your students talk about where they saw perpendicular lines. It could instead be a math journal activity where students draw a picture when they are back in your classroom of the object that illustrates the word.

Students can ask more questions to narrow down the choices and then start guessing objects in the classroom that have parallel lines. Suddenly your students are seeing parallel lines everywhere. Play this game with any terms you need to practice. Here are some ideas:

Use this FREE digital geometry review with white boards to add some interactive geometry game FUN to your unit on polygons, angles, lines and 3-D shapes. This digital resource is a perfect geometry vocabulary review you can use immediately with your second, third, or fourth grade students. No paper needed!

This free geometry vocabulary game was created for a 2nd or 3rd grade class. However, there are also fourth grade geometry vocabulary terms included, such as types of triangles. This resource meets the following common core standards: 2.G.A.1, 3.G.A.1, 4.G.A.1, 4.G.A.2, and 4.MD.C.5

The only difference you will find is the font on the editable introduction slides (see picture below) and the practice question slides. Because this is not a Google font and the text is not secured in order to keep select slides editable, the words on the editable slides will need to be changed to a Google font of your liking.

The New York State Next Generation Mathematics Learning Standards Glossary Grades PreK-8 was designed to support New York State school districts and educators as they implement the New York State Next Generation Mathematics Learning Standards (adopted 2017) beginning in the school year 2022-2023. In New York State, curriculum decisions are determined at each local school district, and this glossary is an optional resource for school districts to utilize. The guidance is provided to support districts with the creation or revision of units of instruction aligned to the NYS Next Generation Mathematics Learning Standards.

Mathematical language provides a common platform for students to explore complex topics and ideas from many perspectives and to construct viable mathematical arguments. The Glossary is intended to provide definitions of some mathematical terms used in PreK-grade 8 level instruction and includes terms found in the New York State Next Generation Mathematics Learning Standards. This non-exhaustive glossary clarifies for students and teachers what is meant by various terms when the New York State Education Department uses them for mathematics. At times, there are alternative definitions for some glossary terms within the mathematical community and some terms/definitions contained within this glossary can be used in different standard areas. However, it is important to use these terms as they are used within the Next Generation Mathematics Learning Standards. After numerous reviews in consultation with NYS educators, we have adopted the mathematics definitions contained in this glossary. This is an optional resource, however, NYSED encourages all teachers to become familiar with these definitions and use them consistently throughout a student's educational program.

Educators from around New York State have helped NYSED build this glossary of mathematical vocabulary pertaining to the Next Generation Mathematics Learning Standards. Creating this glossary was a collaborative effort that gave educators the opportunity to identify what to include and why these definitions are important. Multiple committees of educators spent time to build consensus around the definitions found within.

Do you remember sitting in your high school geometry class, looking through your notes and textbook, trying to remember which theorem or postulate to use? If you asked me today about theorems and postulates, I only remember that there were a lot of them!

Elementary students can be overwhelmed by the sheer number of words to learn and keep straight in their heads! Yet, they NEED this vocabulary to think and reason about geometry just as we needed all those theorems and postulates to do the work back then!

On the back of each card, the student wrote the academic term but also a real-life connection. For example, railroad tracks can help you remember parallel lines; a street intersection can help you remember perpendicular lines, etc.

The cards can be sorted, classified, compared and contrasted, and even alphabetized. The point is to get the students to talk and remember the vocabulary as they manipulate the cards. Later, the cards would be used for the review period or as a resource for independent practice or technology integration.

Another hands-on approach involved an oldie-but-goodie kinesthetic movement approach to show the different types of lines and angles. Students used their arms to show parallel lines, right angles, intersecting lines, etc.

Not only did it reinforce the vocabulary, but they also practiced the attributes (which of course, involves all the previous geometry vocabulary). The students worked on their interactive notebooks as independent practice in place of their math book.

Because the digital notebooks were successful with my students, I created a total of 6 digital interactive notebooks for geometry. They cover plane figures, lines, angles, polygons, quadrilaterals, and triangles.

The digital notebooks are structured in a way that can replace traditional workbooks or math book exercises. But digital notebooks are more than just digital versions of math books. They are enhanced. My digital notebooks come with web and video links the students use to learn and gather information.

Finally, since repetition is one of the keys to learning all this vocabulary, why not have it be fun? This is a game I have used for many years to review all the vocabulary. This is helpful before a test and before standardized testing. It is available in my STORE.

This resource is updated with a new look and now comes with black-and-white versions of the game boards. The games can be played with 2 to 6 players. Here are some pictures of my students using the game boards BEFORE the update.

You can see some of these in action in this post! Each set covers a different geometry concept and gives several different types of practice activities related to each. The bundle is available at a greatly reduced price. Everything you need to teach the geometry standards for grade 4 (and tied to grades 3/5 as well) is included. Print and digital.

Students in 6th grade are building the foundation for the math they will be working on in 7th and 8th grade. Many of the concepts are a continuation of the 6th grade work and dive deeper into the understanding and development leading up to algebra. Students in 7th and 8th grade are preparing themselves for the work they will be completing in high school in both algebra and geometry. These building blocks will be pivotal in their overall understanding and success at the high school level.

1. Number System. In 7th grade, students will fully understand how to interpret and compute all rational numbers. They can add, subtract, multiply, and divide all decimals and fractions, as well as represent percents. They compute both positive and negative numbers using all four basic operations and interpret the meaning of absolute value. In 8th grade, students move beyond rational numbers to irrational numbers. They understand the concept of decimal expansion and can interpret and find both rational and irrational numbers on a number line.
