Locating Numbers on a Number Line with our BBES 3rd Graders The top number in a fraction is called the numerator. 1 3 The bottom number in a fraction is called the denominator. “Denominator” starts with a “D” so look Down at the bottom of the fraction. numerator 5 8 denominator The BIG number next a 1 8 fraction is the WHOLE NUMBER. 3 fraction What is the top number called? 3 The numerator! 4 What is the bottom number called? The denominator! 2 Name the denominator in this fraction. 9 9! 1 Name the numerator in this fraction. 5 1! 6 1 Name the whole number. 9 1! 2 Name the numerator in this fraction. 3 2! 2 6 Name the whole number. 9 6! 7 Name the denominator in this fraction. 12 12! 0 1 1 2 3 4 Count the spaces between the WHOLE numbers on the number line. 0 1 1 2 3 4 Now add ONE to that number… 4+1= 5 0 1 1 2 3 4 That is your denominator! 4+1= 5 0 1 1 2 3 4 5 5 5 5 5 5 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 Count the spaces between the WHOLE numbers on the number line. What is your denominator? 0 1 2 3 4 5 6 7 8 9 1 9 9 9 9 9 9 9 9 9 Is your denominator 9? Let’s see! What’s wrong with this? 9/9 should be the second whole number! We forgot to add 1 to our count! 0 1 2 3 4 5 6 7 8 9 10 10 10 10 10 10 10 10 10 10 10 That’s better! 0 1 What is the DENOMINATOR of your fraction? 0 1 1 2 Count the spaces between the WHOLE numbers on the number line and add 1! 0 1 1 2 So the denominator is 2 + 1 = 3! 0 1 3 3 1 2 3 3 Let’s write in the correct fractions now… 0 1 What is the DENOMINATOR of your fraction? 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 1 First count the spaces in between, and then add 1! 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 1 So 15 + 1 = 16! Your denominator is 16! 0 1 Now fill in the correct fractions! 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 1 0 16 16 16 Nice work! 0 1 What is the DENOMINATOR of your fraction? 0 1 2 3 1 Count up the spaces in between the whole numbers… Now add 1! So 3 + 1 = 4! 0 1 2 3 1 0 4 4 4 4 4 4 Fill in the fractions! 2 3 It doesn’t matter if the WHOLE NUMBERS are 0 and 1…. They might be 2 & 3! 2 3 1 2 You still count the spaces and add 1… 2 3 1 2 (2 + 1 = 3 is the denominator!) 2 2 1 3 2 2 3 3 But you add the WHOLE NUMBER in front of the fractions! 7 8 The whole numbers might be 7 & 8! 7 8 1 2 3 You still count the spaces and add 1! 3 + 1 = 4 is the denominator! 1 2 3 7 4 4 4 8 Is this correct? What did I forget? 1 2 3 7 7 4 7 4 7 4 8 I forget the WHOLE NUMBERS! Let’s fix it together! 1 2 3 4 5 6 7 First find the denominator of your fractions. Count the spaces and add 1! 7 + 1 = 8 is your denominator! 1 2 3 4 5 6 7 8 8 8 8 8 8 8 0 8 8 8 Now fill in your fractions! 1 2 3 4 5 6 7 8 8 8 8 8 8 8 0 8 5 7 1 3 8 8 8 8 8 8 Next, correctly fill in the answers for the fractions at which A, B, C, and D are marked. 1 2 3 4 First find the denominator of your fractions. Count the spaces and add 1! 4 + 1 = 5 is your denominator! 1 2 3 4 5 5 5 5 0 5 5 5 Now fill in your fractions! 1 2 3 4 5 5 5 5 0 5 5 2 4 3 1 5 5 5 5 5 Finally, correctly fill in the answers for the fractions at which A, B, C, and D are marked. 1 2 3 4 5 6 7 8 9 10 11 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 12 12 12 12 12 12 12 12 12 12 12 0 12 12 12 Now fill in your fractions! 1 2 3 4 5 6 7 8 9 10 11 12 12 12 12 12 12 12 12 12 12 12 0 5 11 10 9 12 12 12 12 12 12 12 Finally, correctly fill in the answers for the fractions at which A, B, C, and D are marked. 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!
