  5. What Do I Mean Compare Decimals? When we compare we use terms such as: • Less than < • Greater than > • Equal to =

  6. Half Pipe Results Compare Sara’s score with Danny’s score. • Line Up Decimal Points • Sara: 42.1 • Danny: 42.5 • Add zeroes if needed. • Start at the left and find the first place where the digits are different. Sara’s score was less than Danny’s score.

  7. Let’s Try Using A Number Line 42.0 42.1 42.2 42.3 42.4 42.5 Numbers to the right are greater than numbers to the left. Since 42.5 is to the right of 42.1 we have: 42.5 > 42.1 OR 42.1 < 42.5

  8. Number Line .12 .6 A What is the value of A? To find it you have to identify the number pattern. How do I get from .6 to .12?

  9. Number Line Example • Find ‘a’ on the number line below. • Find ‘b’ on the number line below. 9.0 a 13.0 b 11.5 10.0

  10. Equivalent Decimals • Decimals that name the same number are called equivalent decimals. • 0.60 and 0.6 • Are these the same???

  11. 0.60 0.6 =

  12. Ordering Decimals: 15, 14.95, 15.8, 15.01 • First, line up the decimal points 15.00 14.95 15.80 15.01 • Second, add zeroes if needed. • Finally, compare the decimals. Always start from the left!! • Answer:14.95, 15, 15.01, 15.8

  13. Examples: • Order these numbers from greatest to least • 35.06, 35.7, 35.5, 35.849 • Order these numbers from least to greatest • 0.018, 0.013, 0.28, 0.205, 0.035 • Compare, use these symbols < , >, = • 0.14 0.041 • 0.760 0.76 • 12.23 12.79
