Showing Results for "properties of triangles"

Classifying figures by features is a fundamental geometry skill. Use this lesson plan to teach your students how to categorize triangles by internal angle types. 

Classifying Triangles by Internal Angles

2D shapes are all around us! In this lesson students will explore the properties of four different shapes—triangles, circles, rectangles, and squares! They will learn that they can find these shapes anywhere in the world around us.


Finding All of the Flat Shapes

Roll some dice to introduce the early concepts of associative and commutative properties in addition by composing and decomposing 10. Worksheets and a quiz are included!

Give Me 10!

You'll see angles from every angle! Students will describe and compare different angles they see in everyday situations. Use this lesson on its own or use it as support to the lesson Classifying Triangles by Internal Angles.

Describing Angles

In this lesson, students will use a multi-sensory approach by engaging in a hands on activity with toothpicks to create, explore, and learn about the properties of four different types of angles.

All About Angles

In this lesson, students engage in interesting hands-on activities that help them discover the properties of parallel, perpendicular, and intersecting lines. Your little mathematicians will have a blast as they learn about geometry.

What's My Line?

Practice subtraction with art! Help early learners grasp the concept of "taking away" using drawings. This lesson helps students work toward subtraction with numerals, and the mastery of simple shapes.

Art Subtraction

Sorting takes on a new challenge for students in this activity which engages their critical thinking skills. As students determine defining attributes, they’ll figure out what makes a shape a shape!

Shape Sort

It’s magic! In this lesson, students will “magically” move shapes together to form new shapes. Clay and toothpicks equal hands-on fun! Tangram challenges are provided for those students who need that little extra challenge.

Magical Movement

Discovery is exciting! In this hands-on lesson, your students will discover for themselves the rule behind the commutative property of addition.

Commuting and Computing

In this lesson, your students will become familiar with shapes by identifying them in real life. Your students will love identifying how many sides shapes have by drawing and counting them!

Know Your Shapes!

Adding fractions with unlike denominators just doesn't work like it does when the denominators are the same. Let's make it work! Students will add fractions with unlike denominators with sums between one and two.

Make It Work! Adding Fractions with Unlike Denominators

Your students will have a blast thinking about polygons and making these paintings inspired by Wassily Kandinsky!


Kandinsky Shapes

Your students will learn when to use less than and greater than and how to differentiate the two symbols in this lesson. They will have fun playing the role of the Less Than and Greater Than alligators!

Less Than or Greater Than Alligators

Make a math mystery! In this lesson, help your students understand the relationship between addition and subtraction and how a missing addend word problem is represented with a number sentence.

Mystery Addends: Representing Word Problems

This lesson helps students understand the difference between polygons. It focuses on the root words of these terms to help students make connections to their prior knowledge, making it especially beneficial for ESLs.

Jumping Into Geometry!

Use this lesson with your students to allow them to explore the associative property of multiplication by having deep discussions in small groups. Use this as a stand alone lesson or alongside *Associative Property of Multiplication*.

Explore the Associative Property of Multiplication

Learning about shapes isn't "square" with this lesson! Students will learn what makes up a shape and learn to draw them themselves which will turn into a fun hands-on clay molding activity.

Shape Identification: Bake 'N Buy

Teach your students about the shapes that make up the world around them with this lesson that has them identify shapes in the classroom and in drawn scenes.

The Shape of Me and Other Stuff

This snazzy lesson features Pete the Cat and His Four Groovy Buttons by Eric Litwin. Your students will love practicing their classification skills while playing with buttons of their own.


Button Classification

In this lesson, your students will collect and organize data to make a beautiful bar graph! They will also practice analyzing the graphs with the information they have.

Collect, Organize, Display, Analyze

Animals and spots are used to make multiplication interesting! In this lesson, students will practice multiplying one digit numbers.

Animal Spots: Multiplication Practice

Let's get clapping! Help students extend their knowledge of patterns by using rhythm. After making musical patterns, students will translate the patterns into shape patterns. 

Rhythm Patterns

Teach your students to recognize and use the associative property of multiplication.

Associative Property of Multiplication

Teach your students to predict and explain features of scaled regular shapes.

Shapes to Scale

Teach your students to recognize and use the distributive property of multiplication.

Distributive Property

Identifying shapes and colors will come easily to students after listening to songs, playing bingo, and coloring a worksheet!

Shapes for Kindergarten!

What's in the bag? This fun math lesson involves using defining attributes as clues to draw conclusions. Young learners will have a great time making guesses about different objects and creating their own shape riddles.

Shape Detectives: What's in the Bag?

Your students will love classifying shapes into groups with this simple coloring and graphing lesson. It includes a bunch of fun worksheets and a song to keep young mathematicians engaged.


Classify, Count, and Graph with Shapes

How are quadrilaterals connected? In this lesson, your students will learn about the relationship between quadrilaterals by drawing, defining, and labeling different ones.
