  1. Fraction Number Lines Locating Numbers on a Number Line with our BBES 3rd Graders

  2. Let’s identify the parts of a fraction. The top number in a fraction is called the numerator. 13 The bottom number in a fraction is called the denominator. “Denominator” starts with a “D” so look Down at the bottom of the fraction. 

  3. Let’s review… numerator 58 denominator

  4. What is a whole number? The BIG number next a fraction is the WHOLE NUMBER. 13 8 fraction

  5. Give it a try! What is the top number called? 34 The numerator! What is the bottom number called? The denominator!

  6. Give it a try! 29 Name the denominator in this fraction. 9!

  7. Give it a try! 15 Name the numeratorin this fraction. 1!

  8. Give it a try! 1 69 Name the whole number. 1!

  9. Give it a try! 23 Name the numeratorin this fraction. 2!

  10. Give it a try! 6 29 Name the whole number. 6!

  11. Give it a try! 712 Name the denominator in this fraction. 12!

  12. This is how you label fractions on a number line… 0 1 1 2 3 4 Count the spaces between the WHOLE numbers on the number line.

  13. This is how you label fractions on a number line… 0 1 1 2 3 4 Now add ONE to that number… 4 + 1 = 5

  14. This is how you label fractions on a number line… 0 1 1 2 3 4 That is your denominator! 4 + 1 = 5

  15. This is how you label fractions on a number line… 0 1 55 15 25 35 45 So now just starting counting by 1s, starting with 1. Your WHOLE number will have the same number as the numerator and denominator.

  16. TRY IT! 0 1 Count the spaces between the WHOLE numbers on the number line. What is your denominator?

  17. Uh-Oh! 79 89 99 0 1 19 29 39 49 59 69 What’s wrong with this? 9/9 should be the second whole number! We forgot to add 1 to our count! Is your denominator 9? Let’s see!

  18. One more time! 710 810 910 0 10 10 110 210 310 410 510 610 That’s better! 

  19. YOU’RE NEXT!

  20. Your turn! 0 1 What is the DENOMINATOR of your fraction?

  21. Your turn! 0 1 1 2 Count the spaces between the WHOLE numbers on the number line and add 1!

  22. Your turn! 0 1 1 2 So the denominator is 2 + 1 = 3!

  23. Your turn! 0 1 33 13 23 Let’s write in the correct fractions now…

  24. Your turn! 0 1 What is the DENOMINATOR of your fraction?

  25. Your turn! 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 First count the spaces in between, and then add 1!

  26. Your turn! 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 So 15 + 1 = 16! Your denominator is 16!

  27. Your turn! 0 1 Now fill in the correct fractions!

  28. Your turn! 123456789101112131415 0 1 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 016 1616 Nice work! 

  29. Let’s try another one! 0 1 What is the DENOMINATOR of your fraction?

  30. Let’s try another one! 1 2 3 0 1 So 3 + 1 = 4! Now add 1! Count up the spaces in between the whole numbers…

  31. Let’s try another one! 123 0 1 4 4 4 44 04 Fill in the fractions!

  32. Your turn! 2 3 It doesn’t matter if the WHOLE NUMBERS are 0 and 1…. They might be 2 & 3!

  33. Your turn! 2 3 1 2 You still count the spaces and add 1…

  34. Your turn! 2 3 1 2 (2 + 1 = 3 is the denominator!)

  35. Your turn! 2 3 13 23 2 2 But you add the WHOLE NUMBER in front of the fractions!

  36. Your turn! 7 8 The whole numbers might be 7 & 8!

  37. Your turn! 7 8 2 3 1 3 + 1 = 4 is the denominator! You still count the spaces and add 1!

  38. Look closely… 34 7 14 24 8 What did I forget? Is this correct?

  39. Look closely… 34 7 14 24 8 7 7 7 I forget the WHOLE NUMBERS! Let’s fix it together!

  40. Let’s try some tricky problems together!

  41. Look at the number line below! 1 2 3 4 5 6 7 Count the spaces and add 1! 7 + 1 = 8 is your denominator! First find the denominator of your fractions.

  42. Look at the number line below! 1234567 8 8 8 8 8 8 8 88 08 Now fill in your fractions!

  43. Look at the number line below! 1234567 8 8 8 8 8 8 8 88 08 38 58 18 78 Next, correctly fill in the answers for the fractions at which A, B, C, and D are marked.

  44. Let’s try another one.  1 2 3 4 Count the spaces and add 1! 4 + 1 = 5 is your denominator! First find the denominator of your fractions.
