Welcome to the world of fractions! Today we'll learn how numbers can describe parts of a whole.Let's start with something familiar - a pizza!When we cut a pizza in half, we create two equal parts. Each part represents one half of the whole pizza.In a fraction, the top number is called the numerator. It shows how many parts we're counting. The bottom number is the denominator, showing the total number of equal parts.Let's look at another example - a chocolate bar divided into eight equal pieces.If we take two rows with four pieces each, each row represents one fourth of the whole bar.We can divide any shape into equal parts. Here's how one third looks in different shapes.Remember these important points about fractions: they show parts of a whole, the parts must be equal, and we can use fractions with any shape.Let's learn how to read fractions aloud.Let's start with one fourth. We can also call this one quarter.Here are some common ways to name the bottom number, or denominator. Notice how some numbers have multiple options, like fourth or quarter.Let's compare two fractions using pizzas. Here we have one pizza cut in half, and another cut into quarters.One half is larger than one quarter because when we cut the pizza into more pieces, each piece gets smaller.When comparing fractions with the same denominator, like two fourths and three fourths, we just need to look at the numerators.Three fourths is larger than two fourths because three is greater than two.Let's place these fractions on a number line to compare them all at once.One fourth is at zero point two five...One half is at zero point five...And three fourths is at zero point seven five.So we can see that one fourth is less than one half, which is less than three fourths.Let's review what we've learned about comparing fractions.When we cut something into more pieces, each piece gets smaller. When fractions have the same denominator, we just compare the numerators. And a number line helps us compare any fractions.Thanks for learning about comparing fractions with Spark.E!
