Have you ever heard about fractions? They pop up in many places, like when you share candy or measure something. Let’s explore fractions together!
Hi there! I’m Francis, and I’m here to tell you all about fractions. A fraction is a way to show a part of something. Every fraction has two parts: a numerator and a denominator.
The denominator is the number below the line in a fraction. It tells us how many equal parts the whole thing is divided into. My friend Dennis calls it the “down-ominator” because it’s down below!
The numerator is the number on top of the line. It tells us how many parts we are talking about.
Let’s imagine you have a package with five candy bars. The denominator is 5 because there are five bars in total. If your sister takes four bars, the numerator is 4, and we say she took four-fifths of the candy bars.
Now, how many candy bars do you have left? Just one! So, you have one-fifth of the candy bars left.
Suppose you have a whole candy bar and want to share it with two friends. You need to divide it into three equal parts, called thirds. Each part must be the same size for it to be fair.
To make sure each piece is the same size, you can use a ruler to measure. If each piece is two inches, then everyone gets an equal share!
When we divide something into equal parts, we call these parts congruent. Congruent means the parts are the same size and shape. So, when you share, make sure the pieces are congruent!
Remember, fractions help us understand parts of a whole, and congruent parts make sharing fair and fun!
Fraction Hunt: Go on a fraction hunt around your home or classroom! Look for items that can be divided into equal parts. For example, a pizza, a chocolate bar, or a set of colored pencils. Count how many equal parts each item has and identify the numerator and denominator. Can you find something that can be divided into thirds or fourths?
Build Your Own Fraction Pizza: Use paper plates to create your own fraction pizzas. Draw and cut out different toppings to represent different fractions. For example, cover half the pizza with pepperoni (1/2) and a quarter with mushrooms (1/4). Share your pizza with a friend and explain the fractions you used.
Fraction Story Time: Create a short story about a day in the life of a fraction. What adventures does it go on? How does it help people share things equally? Draw pictures to illustrate your story and share it with your classmates. Think about how fractions make everyday activities fair and fun!
Sure! Here’s a sanitized version of the transcript:

[Music] We’ve heard about fractions at different times. Check out the examples in these rhymes. [Music] I’ll give you half of my candy bar. [Music] To make the carpet fit, I need another quarter of a yard. [Music]
Hi, I’m Francis, and I know a lot about fractions. A fraction is a way of writing a part of a thing or set. All fractions have a numerator and a denominator. The denominator is the number written under the bar or after the slanted line. The denominator tells you how many equal parts the thing or set is divided into. The numerator is the number written on top of the bar or before the slanted line. The numerator tells you the number of parts you are observing.
I have a silly way of remembering which is the denominator in a fraction. Oh, hi Dennis! How do you remember which one is the denominator? I think of it as the “down-ominator.” [Music]
Okay, that’s a good way to remember it. Now let’s look at some examples of how we might use fractions. Suppose you had a package of candy bars that had five candy bars in it. Then the number in the set, or the denominator, would be 5. The numerator would depend on how many of the candy bars you’re talking about. So if my sister came and took four out of the package, then we could say that she took four-fifths of the candy bars.
That’s right! And how much of the package do you have left? Well, there’s one left here, so I have one-fifth of the candy bars left.
Hey, where did you get that whole candy bar? Can I have half? Wait a minute, Newman, there are three of us now, so we should divide it into thirds. Okay, here you can have this little piece.
Well, that’s not fair! I didn’t get a third. All three parts have to be the same size for it to be divided into thirds. Good point, Newman! Let’s get a ruler and a knife. That’s two inches for Dennis, two inches for Newman, and two inches for me. [Music]
And now I get it! You have to divide a candy bar or anything else into parts that are the same size and shape to use a fraction. That’s right! We call parts that are the same size and shape congruent parts. If the parts of an object are the same size and shape, they are congruent.
Let’s say that again in a shorter form to make it a little more fluent: congruence means same size and shape. Congruent means same size and shape. Congruent.
