1. 4.2 Comparing and Ordering Decimals

2. Review How do we compare numbers < Less Than > Greater Than = Equal to We look at place value How do we order numbers decide if we are ordering greatest to least or least to greatest Compare two numbers at a time Place in proper order

3. Quick Practice LEFT Hand  LESS THAN < RIGHT HAND  GREATER THAN > BOTH HANDS  EQUAL TO = 1000 ____ 1,001 < Left Hand 12,435 ____ 12,345 > Right Hand One million ____ 1,000,000 = Both Hands

4. Why are decimals different? What is larger? 0.1 – One Tenth or 0.01 One Hundredth

5. Why are they SO Tricky 0.1 ______ 0.0999999 0.09 ______ 0.001 0.84 ______ 0.84000000 0.0555______ 0.5 6.7 ______ 7.1 > > = < <

6. Steps for Comparing Decimals 1)Line up numbers by place value (Decimal Dave) 2) Start at the LEFT and find the place where the digits are different 3) Compare those digits 4) Put in proper symbol or =

7. Steps for Ordering Decimals 1)Compare the numbers two at a time 2) List them from greatest to least or least to greatest

8. 1) 0.890 _________ 0.9 2) Order from Least to Greatest 0.6 0.66 6.7 0.07 3) Order from Greatest to least 0.4 4.4 0.044 4.44 4) 0.2000 ________ 0.2 < 0.07 0.6 0.66 6.7 4.44 4.4 0.4 0.044 =
