  1. Math 5Comparing and Ordering Decimals part 2 Instructor: Mrs. Tew Turner

  2. In this lesson we will learn how to compare decimals that are written to different place values.

  3. In your Math Notebook Use the boxes below. Put in your own numbers. Use the same directions as before. Try to use mental math. = Math Warm-up = = = What do you notice about your results?

  4. What do you notice about your results? I noticed that the answers were the same. Math Warm-up Why do you think that the answers were the same? Talk to a partner to answer this question.

  5. In the last lesson you learned how compare and order decimals that are written to the same place value. In this lesson we will answer these questions: How can you compare decimals if they are written to different place values? How can you order decimals that are written to different place values?

  6. How can you compare decimals that are written to different place values? Let’s compare the decimals 6.8 and 6.804. Step 1 Line up the decimal points. 6.8 6.804

  7. How can you compare decimals that are written to different place values? Let’s compare the decimals 6.8 and 6.804. Step 2 Add zeros to the end of the number that has fewer decimal places until it is even with the other number. 6.800 6.804

  8. How can you compare decimals? Let’s compare the decimals 6.8 and 6.804. Step 3 Compare digits of the same place value, starting at the left. 6.800 6.804

  9. How can you compare decimals? Let’s compare the decimals 6.8 and 6.804. Step 4 Keep comparing digits as you move to the right until you find digits that are different. 6.800 6.804

  10. How can you compare decimals? Let’s compare the decimals 6.8 and 6.804. Step 5 Compare. 6.800 6.804 Which is bigger?

  11. How can you compare decimals? 6.800 6.804 Which is bigger? 6.804 is bigger than 6.800 In math we say, “6.804 is greater than 6.800.” We write 6.804 > 6.800

  12. Remember in the last lesson you learned that when you see a problem asking you to compare decimals it will look like this: You will have to put in the >,<, or = sign 27.2 27.02

  13. 27.2 27.02 You will have to put in the >,<, or = sign 27.2 27.02 Which is greater?

  14. 27.2 > 27.02 You will have to put in the >,<,= sign 27.20 27.02 Which is greater? 27.20 is greater, so the symbol will open toward it.

  15. 6.34 6.304 0.102 0.51 Try these in your Math Notebook 1.2 1.143 5.92 5.920

  16. 6.34 > 6.304 0.102 < 0.51 Try these in your Math Notebook 1.2 > 1.143 5.92 = 5.920

  17. In the last lesson you learned that ordering decimals is very similar to comparing decimals. It is when you put three or more decimals in order from greatest (biggest) to least (smallest) or least to greatest.

  18. Order the following numbers from least to greatest: 1.506, 1.56, 0.8 Make sure to pay attention to what the problem is asking you to do. This one is asking you to put the numbers in order from the smallest to the largest.

  19. Order the following numbers from least to greatest: 1.506, 1.56, 0.8 Step 1: Line up the decimal points 1.506 1.56 0.8

  20. Order the following numbers from least to greatest: 1.506, 1.56, 0.8 Step 2: Add zeros to the end of the numbers until they all end in the same place value. 1.506 1.560 0.800

  21. Order the following numbers from least to greatest: 1.506, 1.56, 0.8 Step 3: Compare digits of the same place value beginning at the left. 1.506 1.560 0.800

  22. Order the following numbers from least to greatest: 1.506, 1.56, 0.8 Step 3: Compare digits of the same place value beginning at the left. 1.506 1.560 0.800 this is the least

  23. Order the following numbers from least to greatest: 1.506, 1.56, 0.8 Step 4: Continue to compare digits of the same place value beginning at the left. 1.506 this is least 1.560 0.800

  24. Order the following numbers from least to greatest: 1.506, 1.56, 0.8 Step 5: Write the numbers from least to greatest. 0.8, 1.506, 1.56

  25. Order the following numbers from greatest to least: 0.402, 0.42, 0.375, 1.2 Step 1:

  26. Order the following numbers from greatest to least: 0.402, 0.42, 0.375, 1.2 Step 1: Line up the decimal points. 0.402 0.42 0.375 1.2

  27. Order the following numbers from greatest to least: 0.402, 0.42, 0.375, 1.2 Step 2: 0.402 0.42 0.375 1.2

  28. Order the following numbers from greatest to least: 0.402, 0.42, 0.375, 1.2 Step 2:Add zeros to the end of the numbers until they all end in the same place value. 0.402 0.420 0.375 1.200

  29. Order the following numbers from greatest to least: 0.402, 0.42, 0.375, 1.2 Step 3: 0.402 0.420 0.375 1.200

  30. Order the following numbers from greatest to least: 0.402, 0.42, 0.375, 1.2 Step 3: Compare digits of the same place value beginning at the left. 0.402 0.420 0.375 1.200 this is the greatest

  31. Order the following numbers from greatest to least: 0.402, 0.42, 0.375, 1.2 Step 4: 0.402 0.420 0.375 1.200

  32. Order the following numbers from greatest to least: 0.402, 0.42, 0.375, 1.2 Step 4: Continue to compare digits of the same place value beginning at the left. 0.402 0.420 this is the greatest 0.375 1.200

  33. Order the following numbers from greatest to least: 0.402, 0.42, 0.375, 1.2 Step 4: Continue to compare digits of the same place value beginning at the left. 0.402 0.420 this is the greatest 0.375 this is the least 1.200

  34. Order the following numbers from greatest to least: 0.402, 0.42, 0.375, 1.2 Step 5:

  35. Order the following numbers from greatest to least: 0.402, 0.42, 0.375, 1.2 Step 5: 1.2, 0.42, 0.402, 0.375

  36. Try this in your Math Notebook Order from least to greatest 6.01 0, 0.601, 6 .1 Order from greatest to least 4.09, 3.9, 3.09, 4.19

  37. Try this in your Math Notebook Order from greatest to least 6.01 0, 0.601, 6 .1 6.1, 6.010, 0.601 Order from least to greatest 4.09, 3.9, 3.09, 4.19 3.09, 3.9, 4.09, 4.19
