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

2 The top number in a fraction is called the numerator. 1313 The bottom number in a fraction is called the denominator. “ D enominator” starts with a “ D ” so look D own at the bottom of the fraction.

3 numerator 5858 denominator

4 The BIG number next a fraction is the WHOLE NUMBER. 1313 8 fraction

5 What is the top number called? 3434 The numerator! What is the bottom number called? The denominator!

6 Name the denominator in this fraction. 2929 9!

7 Name the numerator in this fraction. 1515 1!

8 Name the whole number. 6969 1! 1

9 Name the numerator in this fraction. 2323 2!

10 Name the whole number. 2929 6! 6

11 Name the denominator in this fraction. 7 12 12!

12 Count the spaces between the WHOLE numbers on the number line. 0 1 12 34

13 Now add ONE to that number… 4 + 1 = 5 0 1 12 34

14 That is your denominator! 4 + 1 = 5 0 1 12 34

15 So now just starting counting by 1s, starting with 1. Your WHOLE number will have the same number as the numerator and denominator. 0 1 1515 2525 3535 4545 5

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

17 Is your denominator 9? Let’s see! 0 1 1919 2929 3939 4949 5959 6969 7979 89899 What’s wrong with this? 9/9 should be the second whole number! We forgot to add 1 to our count!

18 That’s better! 0 10 10 1 10 2 10 3 10 4 10 5 10 6 10 7 10 8 10 9 10

19

20 What is the DENOMINATOR of your fraction? 0 1

21 Count the spaces between the WHOLE numbers on the number line and add 1! 0 1 12

22 So the denominator is 2 + 1 = 3 ! 0 1 12

23 Let’s write in the correct fractions now… 0 1 1313 2323 3

24 What is the DENOMINATOR of your fraction? 0 1

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

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

27 Now fill in the correct fractions! 0 1

28 Nice work! 0 1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 0 16

29 What is the DENOMINATOR of your fraction? 0 1

30 Count up the spaces in between the whole numbers… 0 1 1 2 3 Now add 1! So 3 + 1 = 4 !

31 Fill in the fractions! 0 1 1 2 3 4 4 4 4 0404

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

33 You still count the spaces and add 1… 2 3 12

34 (2 + 1 = 3 is the denominator!) 2 3 12

35 But you add the WHOLE NUMBER in front of the fractions! 2 3 1313 2323 2 2

36 The whole numbers might be 7 & 8! 7 8

37 You still count the spaces and add 1! 7 8 1 23 3 + 1 = 4 is the denominator!

38 Is this correct? 7 8 1414 What did I forget? 2424 3434

39 7 8 1414 I forget the WHOLE NUMBERS! 2424 3434 Let’s fix it together! 7 77

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

42 1 2 3 4 5 6 7 Now fill in your fractions! 8 8 8 8 8 8 8 8 0808

43 1 2 3 4 5 6 7 Next, correctly fill in the answers for the fractions at which A, B, C, and D are marked. 8 8 8 8 8 8 8 8 0808 5858 7878 1818 3838

44 First find the denominator of your fractions. Count the spaces and add 1! 4 + 1 = 5 is your denominator! 1 2 3 4

45 Now fill in your fractions! 1 2 3 4 5 5 5 5 0505 5

46 Finally, correctly fill in the answers for the fractions at which A, B, C, and D are marked. 1 2 3 4 5 5 5 5 0505 5 2525 4545 3535 1515

47 First find the denominator of your fractions. Count the spaces and add 1! 11 + 1 = 12 is your denominator! 1 2 3 4 5 6 7 8 9 10 11

48 Now fill in your fractions! 12 0 12 12 12 12 12 12 12 12 12 12 12 12

49 1 2 3 4 5 6 7 8 9 10 11 Finally, correctly fill in the answers for the fractions at which A, B, C, and D are marked. 12 0 12 12 12 12 12 12 12 12 12 12 12 12 5 12 11 12 10 12 9 12

50 A quiz will be handed out to you. Do your best, and TAKE YOUR TIME! Remember to use the strategies we learned as a class. Good luck!
