Hello and welcome! Today, we’re going to learn about something really cool called symmetry. Imagine a butterfly named Mia. Mia is beautiful because her wings are symmetrical. But what does that mean?
Symmetry is when you can draw an imaginary line through something, and both sides look exactly the same. This line is called the line of symmetry. If you fold the object along this line, the two parts will match perfectly!
Let’s look at some examples. Think about a starfish. If you draw a line from the top to the bottom and place a mirror on that line, one side looks just like the other. The starfish is symmetrical! In fact, a starfish has five lines of symmetry because you can draw lines from different points and still get matching halves.
Now, let’s look at a rock. If you try to draw a line through the rock, you won’t find any way to make the two sides identical. This means the rock is asymmetrical, which means it has no lines of symmetry.
Did you know some letters are symmetrical too? Look at the letter “A.” If you draw a line down the middle and fold it, both sides match. So, “A” has one line of symmetry. The letter “H” is even more special because you can fold it both vertically and horizontally, giving it two lines of symmetry!
Let’s explore symmetry in shapes. A square is a great example. If you draw a line from top to bottom or side to side, and fold it, the parts match perfectly. A square also has diagonal lines of symmetry, making a total of four lines of symmetry!
Now, think about a circle. A circle is super special because it has infinite lines of symmetry. You can draw a line through the center in any direction, and both sides will always match.
There are so many symmetrical objects around us. Go on a little adventure and see how many you can find! Remember, symmetry is all about finding those magical lines that make two sides look the same.

Symmetry Hunt: Go on a symmetry hunt around your home or classroom. Look for objects that have lines of symmetry. Can you find a book, a leaf, or a piece of furniture that is symmetrical? Draw a picture of each object and show where the line of symmetry is. Share your findings with a friend or family member and see if they can find more symmetrical objects!
Symmetrical Art: Create your own symmetrical art! Fold a piece of paper in half and draw half of a picture on one side of the fold. Then, unfold the paper and try to complete the other half of the picture so that it is symmetrical. You can draw a butterfly, a heart, or even your own creative design. Once you’re done, color it in and display your symmetrical masterpiece!
Letter Symmetry Challenge: Write down the alphabet on a piece of paper. Next to each letter, draw its line of symmetry if it has one. Which letters have one line of symmetry? Which have two? Are there any letters that are asymmetrical? Discuss with a partner why some letters have more lines of symmetry than others.
Sure! Here’s a sanitized version of the YouTube transcript:

Hello and welcome to Tutoring Hour! In this video, join me, Mia the Butterfly, as we explore symmetry with plenty of examples. Let’s begin with this picture of mine. I owe my beauty to my symmetrical shape. Yes, symmetry is our topic for today!
Let me explain: think of an imaginary line that can divide this picture into two identical parts. Now, let’s fold the part on the right over the left. The two parts overlap completely, so we can conclude that the picture is symmetrical. An object is symmetrical if it can be divided into two identical halves; one half is the reflection of the other half. The imaginary line that divides an object into two identical halves is called the line of symmetry or the axis of symmetry.
Now, let’s take a look at another interesting example: the starfish. We’ll draw a dotted vertical line from this point and then place a mirror on the dotted line. This half is the reflection of the other half, isn’t it? We can conclude that the starfish is symmetrical. You may ask if there can be more than one line of symmetry, and the answer is yes! We can draw lines from each of these points, so the starfish has five lines of symmetry.
Now, look at this rock. Let’s draw a vertical line. We cannot divide it into two identical parts. Let’s try a horizontal line. The parts are not identical. No matter which way we draw the line, we do not get identical parts. Hence, we can conclude that the rock has no lines of symmetry; it is asymmetrical.
Let’s try with a few letters of the alphabet. Take a look at the letter “A.” If you fold it along this vertical line, both sides are identical. It has one line of symmetry. Now take the letter “H.” It can be folded both horizontally and vertically, so it has two lines of symmetry.
Now, let’s understand symmetry with a few 2D shapes. Is a square symmetrical or asymmetrical? Let’s draw a vertical line. If we fold the square along this line, one half overlaps the other completely. This shows that the square has a vertical line of symmetry. Now let’s try a horizontal line. When folded along this line, the upper half overlaps the lower half. This shows that a square also has a horizontal line of symmetry. Finally, let’s fold it along the diagonals. The parts overlap completely, so we can conclude that a square has four lines of symmetry.
The circle, however, has infinite lines of symmetry, provided that each of these lines passes through the center.
I think that’s enough for now, but there’s a whole world out there filled with symmetrical objects. Go explore! Don’t forget to visit www.tutoringhour.com for more practice. Like and subscribe for regular updates. Thanks for watching!
