## Equivalent Fractions on a Number Line

00:00

Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

## Fractions of a Set

00:00

Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.

## Fractions Equivalent to Whole Numbers

00:00

Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

## Fractions - Parts of a Whole

00:00

Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.

## Equivalent Fractions

00:00

## Comparing Fractions

00:00

Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

## Fractions Using a Number Line

00:00

Understand a fraction as a number on the number line; represent fractions on a number line diagram.

## Area and Fractions

00:00

Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.

## Modeling Division of Fractions

00:00

Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. For example, create a story context for (2/3) ÷ (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) ÷ (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In general, (a/b) ÷ (c/d) = ad/bc.) How much chocolate will each person get if 3 people share 1/2 lb of chocolate equally?

## Adding Fractional Parts of 10 and 100

00:00

Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100.4 For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100.
