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.

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.

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!

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.

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.

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.

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.

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!

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.

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!

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

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.

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

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!

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.

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.

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.

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.

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.

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.

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.

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

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.

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

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

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

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

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.

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.

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