  1. Comparing and Rounding Decimals Christine Berg Edited V Hamilton

  2. Decimal Places • 1000 = thousand • 100 = hundred • 10 = ten • 1 = one • 0.1 = tenth • 0.01 = hundredth • 0.001 = thousandth • 0.0001 = ten-thousandth

  3. Reading Decimals Step 1: Read the number before the decimal point

  4. Reading Decimals Step 2. Read the decimal point as “and”

  5. Reading Decimals Step 3: Read the number after the decimal place

  6. Reading Decimals Step 4: Follow the second number with the place value of the last digit Hint

  7. Reading Decimals Hint .05 Draw and imaginary line underneath

  8. Reading Decimals Hint.05 Place a 1 under the decimal Place zeroes under each of the following numbers . 05 100

  9. Reading Decimals . 05 100 is read as five hundredths

  10. Comparing Decimals • Decimal Models • Equivalent Decimals • Number Line

  11. Decimal Models Tenth Hundredth

  12. Equivalent Decimals • Decimals that represent the same value • Example: 0.6 is equivalent to 0.60 0.6 = 0.60

  13. Terminal Zeroes • Zeroes as last digit(s) of a number can be removed 0.6 = 0.60

  14. Equivalent Decimals 0.6 0.60

  15. Comparing Decimals Step 1: Underline the first number that is different in the numbers being compared

  16. Comparing Decimals Step 2: Add terminal zeros so there are the same number of decimal places

  17. Comparing Decimals Step 3: Remove the decimal point

  18. Comparing Decimals Step 4: Order numbers depending on the directions given

  19. Comparing Decimals Step 5: Replace decimal point and remove terminal zeroes

  20. Which is greater: 0.6 or 0.58 ?

  21. 0.60 0.58 0.6 > 0.58

  22. Which is greater: 0.6 or 0.58 0.6 0.58

  23. Rounding Decimals Step 1: Underline decimal place we are rounding

  24. Rounding Decimals Step 2: Circle the number to the right of the underlined decimal place

  25. Rounding Decimals Step 3: If circled digit is greater than or equal to 5, then round the underlined number up (add one)

  26. Rounding Decimals Step 4: If circled digit is less than or equal to 4, leave the underlined number the same

  27. Rounding Decimals Try these: 1)Round 1.05 to the nearest tenth 2) Round 0.123 to the nearest tenth

  28. Rounding Decimals Answers: 1) 1.1 2) 0.12

  29. In your Own Words Describe what you learned today about either reading OR rounding decimals.
