In this lesson, we will learn:

- How to use fractions to talk about sets of objects
- How to use division and multiplication to solve for fraction of a set

- We can use
**fractions**to talk about**sets of objects**. We can use images or just simplify to a simple shape like a circle. - Ex. If Austin has 8 jellybeans and he wants to give $\large \frac{1}{4}$ to her, how many jellybeans will he give?

- By making 4 equal groups and then giving just 1 of those groups, we realize that there is 2 in each group, so he gave his sister 2 jellybeans.

- We can use
**division**and**multiplication**to find the fraction of a set - Ex. After giving his sister jellybeans, Austin has $\large \frac{3}{4}$ of his 8 jellybeans left.

- Step 1: divide 8 into 4 equal groups $\, \longrightarrow \,$ 8 ÷ 4 = 2
- Step 2: take the result and multiply by 3 groups $\, \longrightarrow \,$ 2 × 3 = 6

- The formula for a fraction of a set:
- following the format:
- divide the denominator and multiply the numerator

**Grouping circles for fractions of a set**

For the set of circles, answer the sentence equation by:- Drawing circles to make equal groups
- And then drawing a box around the given amount

a)$\large \frac{2}{3}$ of 12 is ____b)$\large \frac{4}{5}$ of 15 is ____ - 3.
**Fractions of a set with division**

____ ÷ ____ = ____b)$\large \frac{1}{2}$ of 18 is ____

____ ÷ ____ = ____ - 4.
**Fractions of a set with multiplication and division**

____ ÷ ____ × ____ = ____b)$\large \frac{5}{6}$ of 24 is ____

____ ÷ ____ × ____ = ____ - 5.
**Word problems for fractions of a set**

Use drawings to help you answer the word problems.a)Raine has 20 socks. $\large \frac{3}{10}$ of the socks are yellow. How many socks are yellow?b)11 children are on the playground. $\large \frac{6}{11}$ of the children are boys. How many girls are on the playground?c)Eli has 21 marbles. $\large \frac{2}{7}$ of the marbles are blue. How manyblue marbles does Eli have?__not__
