  1. MathGrade 4 Mrs. Ennis Comparing Fractions Lesson Nineteen

  2. 2,687 + 8,903 = H – 127 = 279 7 x D = 56 7 x 80 = 8 x 70 = 6. Number of centimeters in two and a half meters

  3. 7. Janie traded 18 dimes and 9 nickels for quarters. How many quarters did she get? 8. Put >,<, = in the box: 40,000 + 16,000 + 800 + 6 50,000 +6000 + 6 + 800

  4. Jill placed 4 pennies on each page of a 20 page photo album and had 16 extra pictures. How many total pictures did she have? If each car will hold 1 driver and 5 students, how many cars will be needed to take Mrs. Cook’s 24 students on their field trip?

  5. Fractions are everywhere. You just have to look around!

  6. Comparing Fractions

  7. Fraction Notation The number above the bar is the numerator. The number below the bar is the denominator. The fraction one-third is written like this: Numerator 1 3 Denominator

  8. How do we compare fractions? First, we make sure that the parts we are comparing are parts of the same whole. X

  9. Equivalent Fractions Whole Halves Thirds Fourths Fifths Sixths Eighths Ninths Tenths Twelfths

  10. How do we compare fractions? < 4/8 5/8

  11. How do we compare fractions? < 2/5 4/5

  12. How do we compare fractions? > 8/9 6/9

  13. How do we compare fractions? > 6/10 4/10

  14. How do we compare fractions? > 6/8 4/8

  15. How do we compare fractions? < 2/10 4/10

  16. How do we compare fractions? > 5/6 3/6

  17. How do we compare fractions? < 2/4 3/4

  18. Comparing Unit Fractions

  19. Unit Fractions are fractions with a numerator of 1. They show one part of the whole. 1/8 1/4 1/6

  20. The larger the denominator, the smaller the fraction. 1/8 1/4 1/6

  21. So, 1/8 < 1/6 < 1/4 1/8 1/4 1/6

  22. So, 1/3 >1/5 > 1/10 1/10 1/5 1/3

  23. Let’s try some!

  24. So, 1/5 1/8 > 1/5 1/8

  25. So, 1/2 1/3 > 1/2 1/3

  26. So, 1/5 1/4 < 1/5 1/4

  27. So, 1/3 1/6 > 1/3 1/6

  28. 1/6 1/8 >

  29. 1/4 1/2 <

  30. 1/10 1/6 <

  31. 1/5 1/8 >

  32. What happens if we have the same numerator and different denominators? 3/5 3/8 >

  33. 4/5 4/8 >

  34. So, 1/8 < 1/4 < 1/2 1/4 1/2 1/8 0 1

  35. 2/4 2/8 >

  36. 2/6 2/4 <

  37. 4/10 4/5 <

  38. 6/8 6/10 >

  39. Practice Order the following fractions from greatest to least. 1/5 1/3 1/7

  40. Practice Order the following fractions from greatest to least. 1/4 1/8 1/2
