The document provides examples and word problems for comparing, ordering, rounding, multiplying, dividing, and estimating whole numbers. It also includes word problems involving calculating totals, averages, differences, and applying math operations to real world scenarios like sales, farming, and purchasing a truck.

1. Whole Number Round up!

2. We’re going to wrangle up our brains and review… Comparing Ordering Rounding Multiplying Dividing Estimating Word Problems

3. Let’s start with comparing… When you compare whole numbers, line up the digits and compare from left to right! 12,034,922 ____ 21,411,891 1 2,034,922 2 1,41 1,891 The 2 is bigger than 1, so 12,034,922 < 21,411,891

4. Work these! 112,457,344,722 ____ 121,989,445 453,621,780,200 ____ 453,612,899,533 33,299,873,445 ____ 33,299,873,445 431,459,244 ____ 413,495,442,100

5. Ordering… Follow the same steps for comparing! Line up the numbers! Compare from left to right!

6. Work these! 314,563,299; 314,651,543; 399,432,672 242,633,232; 453,682,573; 97,342,356 349,543,121; 452,827,245; 864,923,435 342,678,210; 232,792,299; 232,643,211

7. Rounding… Underline the rounding place value. Look to the right of the rounding place. If the number is 5 or greater ROUND UP! If the number is less than five, STAY THE SAME! Numbers to right of the rounding place turn to zeroes.

8. Work these! Round 219,546,933,921 to the nearest million. Round 549,611,858,292 to the nearest hundred billion. Round 400,293,202,355 to the nearest ten thousand. Round 200,399,101,444 to the nearest ten million.

9. And these… Round 49,203,502,483 to the nearest thousand. Round 433,920,391,281 to the nearest hundred. Round 48,178,742,787 to the nearest hundred million.

10. Multiplying! Line up the digits from the right! Start multiplying with the ones. When you move to the tens, put a zero in the ones place!! Add up your answers and put in your commas! 2347 x 32 4694 7041 0 75,104

11. Work these! 5,299 x 92 8,931 x 74 4,295 x 28 6,326 x 86

12. Divide Divide Multiply Subtract Bring down! Repeat! 1104 r26 57)67954 -57 109 -57 25 - 0 254 -228 26

13. Work These! 45,671 ÷ 49 51,592 ÷ 78 85,293 ÷ 36 62,476 ÷ 54

14. Estimating… Round numbers to the highest place value. Perform the operation. 32,582 – 19,563 30,000 – 20,000 = 10,000

15. Work these! Estimate… 5,673 x 43 37,299 + 4,349 53,459 ÷ 257 49 – 23

16. Word Problems! Read it! Plan it! Solve it! Check it! Sarah ran 3 miles last week and 2 miles this week. How many miles has she run in all? 3 + 2 = 5

17. Work these… Mary sells boots at a store for $35 each. If she sold 4,328 pairs last month, what was her profit?

18. Jack has 516 cows. He has decided to put them into 4 separate pastures. How many cows will he put in each pasture?

19. Micah has 413 chickens. Chase has 378 chickens. How many more chickens does Micah have?

20. Tara made 412 cookies for a party. If there are 97 guests, how many cookies can each guest have?

21. There are 45 cows in Pasture A, 75 cows in Pasture B, and 52 cows in Pasture C. If each cow eats 37 pounds of feed each week, how many pounds of food does Farmer Nathan need to buy for one week? How many pounds does he need to buy for one year?

22. Nathaniel has 500 bales of hay. If he splits the bales between 4 other farmers, how many will he have leftover?
