Presentation Transcript

  1. Comparing and Ordering Fractions • Please order these fractions from greatest to least. • 2/3 • 1/8 • 2/6

  2. Objective • Compare and order fractions.

  3. Comparing Two Fractions 8 ___ 9 8 ___ 9 So, < 8 < 8 9

  4. Let’s Practice! • http://www.xpmath.com/forums/arcade.php?do=play&gameid=8

  5. We can use number lines to help us order fractions. Let’s practice! Finding Fractions on a Number Line

  6. Finding Fractions on a Number Line • This number line breaks one whole into fourths. • Where would ¼ be on the number line? • What about 4/4?

  7. Finding Fractions on a Number Line • How many sections does this number line break one whole into? • Can you locate where 1/8 would be? • Name a fraction in eighths that is between ½ and ¾.

  8. Finding Fractions on a Number Line • What does this number line show? • Where would 7/9 be? • What fraction is between 1/9 and 2/9?

  9. Finding Fractions on a Number Line • How would you explain this number line using words? • Can you find 3/5? • Can you mark a fraction larger than 4/5 on the number line?

  10. Finding Fractions on a Number Line • What type of number line is this? • Can you order 5/8, ¼, 2/3, and 3/16 on this number line?

  11. Which fraction is closest to 3/10? 3/5 1/6 3/15 2/3 • Can you explain why?

  12. The Answer! 3/10 = 9/30 3/5 = 18/30 1/6 = 5/30 3/15 = 6/30 2/3 = 20/30

  13. Mini-Quiz • Which fraction is between ¼ and ½ on a number line? • 3/5 • 2/10 • 9/16 • 3/8

  14. Ordering Fractions • Use the LCM to find a common denominator. • Find equivalent fractions using the common denominator. • List the new fractions from least to greatest. • List the original fractions from least to greatest.

  15. Order these fractions from least to greatest: • 7/9 • 5/6 • 2/3 • 1/2

  16. 7/9 = 14/18 5/6 = 15/18 2/3 = 12/18 ½ = 9/18 Ordered from least to greatest: 9/18 12/18 14/18 15/18

  17. Original fractions ordered from least to greatest: • 1/2, 2/3, 7/9, 5/6

  18. What fraction is greater than ¾? • 7/12 • 5/8 • 2/3 • 7/9

  19. Web practice activity! • Balloon Pop Fractions

  20. Are You Stuck? • Find a common denominator • Convert to decimals • Divide numerator by denominator • Draw and use a number line • Draw pictures of the fraction
