5. Warm Up Complete the patterns. 2, 8, ___, 20, ___, 32, 38, __
2, 4, 8, ___, 32, ___
3, 9, ___, 81, ___

6. Think and Write
In the last lesson, you estimated to the nearest ten to solve problems with large numbers in the hundreds. How can you use estimation with numbers in the thousands?

7. Today’s Lesson
In this lesson, you will use multiplication facts and place value to estimate quotients of multi-digit division problems.
Let’s look at the Envision Video for this lesson and take the quiz.

8. Rounding Thousands
When you round to the nearest tens, you look at the ones place.
To divide and round numbers in the thousands, round to the nearest hundred.
What digit will you look to if rounding to the nearest hundred?

9. Practice! Round these thousands numbers to the nearest hundred. 4,360
9,225
6,139
3,894
5,748

10. Solving Larger Equations
4794 ÷ 8
First, round 4,794 to the nearest hundred.
It is much easier to solve 4800 ÷ 8. Think of the pattern: 48 ÷ 8 = 6
480 ÷ 8 = 6
4800 ÷ 8 = 6

11. Solving Equations Practice!
Estimate by rounding to the nearest hundred, then divide.
6289 ÷ 9
4218 ÷ 7
3496 ÷ 5
2433 ÷ 8

12. Problem 1
Edward has $ He wants to divide it among 8 different bank accounts. About how much will Edward put into each account?

13. Problem 2
There are boxes of waffles to be divided equally among 8 grocery stores. About how many boxes of waffles should each store receive?

14. Problem 3
Mary has to drive miles to visit her aunt. If she divides the drive equally between 2 days, about how many miles will she drive each day?

15. Lesson Wrap Up
In this lesson, you learned that mentally computing with multiples of ten will help you estimate the quotient of a multi-digit division problem.
