ClassX Video Lessons Youtube Channel Virtual Elementary School Grade 2 Math Song: Do You Know Your Polygons?
Polygons are special shapes made up of straight lines. These lines connect to form a closed shape. Each place where two lines meet is called a vertex. Let’s learn about some cool polygons!
A triangle is a polygon with three sides. It has three vertices, which are the points where the sides meet. Imagine a slice of pizza or a mountain peak—those are shaped like triangles!
A quadrilateral is a polygon with four sides. It also has four vertices. Think about a square or a rectangle; these are both types of quadrilaterals. They are everywhere, like in windows and books!
A pentagon is a polygon with five sides and five vertices. A famous example is the shape of a soccer ball panel or a home plate in baseball.
A hexagon is a polygon with six sides and six vertices. You can find hexagons in honeycomb patterns made by bees. They fit together perfectly!
A heptagon is a polygon with seven sides and seven vertices. It’s not as common as some other shapes, but you might see it in some fun designs or art.
An octagon is a polygon with eight sides and eight vertices. A stop sign is a great example of an octagon. Next time you see one, count the sides!
Did you know that polygons can have more than eight sides? They can have as many sides as you can imagine! The more sides they have, the more they look like a circle.
Polygons are everywhere around us. Look around your home or school and see how many different polygons you can find!
Polygon Hunt: Go on a polygon hunt around your home or school. Take a piece of paper and draw the different polygons you find. Can you spot a triangle, quadrilateral, pentagon, hexagon, heptagon, or octagon? Try to find at least one example of each. Share your findings with your classmates and see who found the most unique polygons!
Build Your Own Polygon: Use craft sticks, toothpicks, or straws to create your own polygons. Connect them with clay or playdough at the vertices. Try making a triangle, quadrilateral, pentagon, and hexagon. Count the sides and vertices of each shape to make sure they match the definition of the polygon you are building. Can you create a heptagon or an octagon?
Polygon Story Time: Imagine you are a polygon living in a world of shapes. Write a short story about your adventures. What kind of polygon are you? Do you have any polygon friends? What do you do in your polygon world? Share your story with the class and illustrate it with drawings of the polygons you meet in your story.

—
A triangle is a shape with three sides. It’s a polygon made of straight connecting lines, where the lines meet at a point called a vertex. A triangle has three vertices.
Quadrilaterals are shapes with four sides. They are polygons made up of straight connecting lines, where the lines meet at a vertex. A quadrilateral has four vertices.
A pentagon is a shape with five sides. It’s a polygon made of straight connecting lines, where the lines meet at a vertex. A pentagon has five vertices.
A hexagon is a shape with six sides. It’s a polygon made of straight connecting lines, where the lines meet at a vertex. A hexagon has six vertices.
A heptagon is a shape with seven sides. It’s a polygon made of straight connecting lines, where the lines meet at a vertex. A heptagon has seven vertices.
An octagon is a shape with eight sides. It’s a polygon made of straight connecting lines, where the lines meet at a vertex. An octagon has eight vertices.
