1. Team Task
You will have FIVE minutes to work together as a team. First, you will solve individually and then come together as a team.
Each person should work on his/her slate to show your work.
Each person will have his/her own group job.
At the end of the time I will randomly call on one person who will share out.

2. Let’s collaborate!
A stadium can hold 5,028 people. In one section 496 people bought tickets, 828 people sat in another section, and 2,467 people sat in the third section.
Rounding each number to the nearest hundred, about how many seats were left in the stadium?
Each student needs to solve the problem. Then discuss within your group.

Rounding is when you reduce (or lessen) the digits in the number while trying to keep the value the same.
Rounding makes it easier to do math problems.

6. Think about this...
Let’s say you stop at QT for some snacks. You only have $5 and want to buy a few items. You plan to get a drink which is .99¢, a candy bar which is $1.29, and a bag of chips which is $ Will you have enough money?
If you round the cost of each item (up or down depending on the amount) you can see if you will have enough money.

7. Let’s try...
.99¢ drink
$1.29 candy bar
$1.99 bag of chips
This rounds to a $1.
This rounds to a $1.
This rounds to be $2.
If I add them all up, I will spend about $4. I should have enough money to purchase all the items.

8. Rounding In that last example, we rounded to the nearest dollar value.
This week while rounding, we are going to be told to round to specific place values.
We must know our place values to help us round.

9. Place Values
In order to round to a specific place value, we need to first find out where the place value is located.
Let’s take a look...

10. Lastly, all the other numbers to the right become zeros.
Let’s review our rules
First circle the place value you are asked to round to.
Second, underline the number to the RIGHT.
If the number is 0-4, the circled number stays the same.
If the number is 5-9, the circled number goes up one.
Lastly, all the other numbers to the right become zeros.

11. 8 7 3 What if... Round 873 to the nearest ten
stays the same
Round 873 to the nearest ten
First circle the digit in the ten’s place value
Next, underline the digit to the RIGHT.
0-4 the circle number stays the same
5-9 the circle number goes up
Flex your muscles and be a hero
all the other numbers become a zero
