8. Let’s Compare Numbers

9. Comparing number Symbols!

10. Take a look! One Saturday morning, Mirabel and her mother decided to bake some cookies for their share in the church activity for children in their community. Mirabel baked 250 cookies while her mother baked 375 cookies. Let us compare number of cookies baked by Mirabel and her mother. Given: Mirabel – 250 cookies Mother – 375 cookies 250 ones tens hundreds 375 ones tens hundreds

11. 250 ones tens hundreds 375 ones tens hundreds hundreds tens ones 2 5 3 7 5 Take Note! In comparing numbers, you should do it from right to left! In this example, since 3 hundreds is greater than 2 hundreds, thus, 375 is greater than 250.

12. Compare 6 721 and 6 975 What’s the highest place value in the given numbers? thousands hundreds tens ones 6 7 2 1 6 9 7 5 Step 1: Make a tabular representation of the numbers. Step 2: Compare the numbers in the thousands place thousands hundreds tens ones 6 7 2 1 6 9 7 5 6 = 6 Since the thousands place are equal, w need to compare the hundreds place.

13. Compare 6 721 and 6 975 What’s the highest place value in the given numbers? Step 1: Make a tabular representation of the numbers. Step 2: Compare the numbers in the thousands place thousands hundreds tens ones 6 7 2 1 6 9 7 5 7 hundreds < 9 hundreds 7 hundreds is less than 9 hundreds Step 3: Compare the numbers in the hundreds place 6721 < 6975

14. Compare 3 898 and 3 862 What’s the highest place value in the given numbers? thousands hundreds tens ones 3 3 8 8 9 6 8 2 3 898 ______ 3 862  

15. Compare 5 401 and 5 566 What’s the highest place value in the given numbers? thousands hundreds tens ones 5 5 4 5 6 1 6 5 401 ______ 5 566  

16. Compare 80 436 and 48 721 What’s the highest place value in the given numbers? ten thousands thousands hundreds tens ones 8 4 8 4 7 3 2 80 436 ______ 48721 6 1  

17. Compare 29 992 and 29 000 + 992 What’s the highest place value in the given numbers? ten thousands thousands hundreds tens ones 2 2 9 9 9 9 9 9 29 992 ______ 29 000 + 992 2 2  

18. Compare 269 324 and369 324 What’s the highest place value in the given numbers? Hundred thousands ten thousands thousands hundreds tens ones 2 3 6 6 9 9 3 3 269 324 ______ 369 324 2 2 4 4  

19. Compare the numbers by writing the correct symbol. hundreds tens ones 8 6 2 8 4 4 862 ___ 844 hundreds tens ones 7 2 1 7 4 9 721 ___ 749 thousands hundreds tens ones 9 8 1 5 9 3 7 2 9815 ___ 9372 thousands hundreds tens ones 3 4 6 8 7 8 9 2 3468 ___ 7892        

20. Let’s Arrange Numbers

21. Can you easily distinguish which number is the greatest or which number is the least? 466 346 573 672 Compare two (2) numbers at a time 466   346   346 573 573   672 346 466 573 672      

22. Rearrange the given numbers from greatest to least 2 435 4 657 3 546 2 453 4 1 2 3 12 543 12 354 12 345 12 453 1 3 4 2 243 765 243 675 243 654 243 564 1 2 3 4

23. Rearrange the given numbers from least to greatest 435 765 457 879 484 675 564 435 1 2 3 4 52 563 45 231 54 514 57 473 2 1 3 4 86 684 68 864 78 543 39 342 4 2 3 1

24. Compare the numbers by writing the correct symbol 785 978 795 978 456 089 449 897 306 587 360 567 8 000 + 60 000 + 900 + 20 + 1 90 000 + 7 000 + 80 + 300 100 + 6 + 1 000 + 40 000 + 5 000 40 000 + 5 000 +

25. Answer the following Using the digits 2, 4, 7, 5 and 8, what is the least number you can make? 24 578 Using the digits 2, 4, 7, 5 and 8, what is the greatest number you can make? 87 542

26. Answer the following Use the numbers and find the least and the greatest. Fill in the table least greatest 2, 4, 6 9, 7, 7, 1 6, 0, 5, 2, 2 8, 8, 1, 3, 4 6, 7, 8, 9, 0, 2 246 426 1 779 9 771 20 256 65 220 13 488 88 431 206 789 987 620

27. Read and solve each problem! Dino has 50 marbles. Daniel has 75 marbles. Compare the number of marbles. Marie has 250 beads. Her sister has 175 beads. Compare the number of beads. Lily collected 1 378 small shells and 1 005 big shells. Compare the number of shells 50 < 75 250 > 75 1 378 > 1 005
