  1. Today we will represent mixed numbers on a number line. • identify- locate; find • represent- draw and label • fraction - represents part of a whole or part of set; top number is the numerator, bottom number is the denominator. • Mixed Number-has a part that is a whole number and a part that is a fraction. Concept

  2. 20 24 24 20 1 2 3 8 2 5 8 5 40 10 40 40 40 40 40 40 40 5 4 8 When will I EVER do this? How much of my Hershey Bar would you like? 0 1

  3. 3 4 fraction a number that shows part of a whole or part of a set Part of a whole = The denominator, the number on the bottom, gives the total number of parts. The numerator, the number on the top, gives the number of parts being used. Three out of a total of four squares are blue. Three fourths of the box is blue. APK

  4. 3 4 fraction Part of a set Three out of four boxes are blue. APK

  5. 20 100 fraction Twenty out of 100 boxes are blue. APK

  6. 1 5 fraction One out of five pie pieces are blue . APK

  7. Mixed Number • A mixed number has a part that is a whole number and a part that is a fraction. 3 1 = 4

  8. What is the mixed number? 3 = 3 4

  9. What is the mixed number? 3 = 4 4

  10. What is the mixed number? 1 = 5 2

  12. Why is it important that we can represent mixed numbers on a number line? • Being able to represent mixed numbers on a number line helps visualize, or see, the answer to a problem. • Number lines help us compare and order numbers. What are other reasons why it is important we can identify fractions on a number line? IMP

  13. Representing mixed numbers on a number line. Step 1: Look at the number line Step 2: Look at the mixed number you are going to represent (place) on the number line. Step 3: If necessary, label all the points on the number line Step 4: Place the point on the number line. A . Represent point A at 1 ¼ .

  14. Identifying mixed numbers on a number line. Step 1: Look at the number line Step 2: Look where on the number line the point is located Step 3: If necessary, label all the points on the number line Step 4: Write the place where the point is located X . Represent point X at 2 ¼ .

  15. Identifying mixed numbers on a number line. Step 1: Look at the number line Step 2: Look where on the number line the point is located Step 3: If necessary, label all the points on the number line Step 4: Write the place where the point is located B . Represent point B at 2 ¾ .

  16. Let’s review what we learned about representing mixed numbers on a number line. A picture of a line where each point represents a real number and each number a point. What is a number line? Determine the value of each segment and then count the number of segments being used. How do you locate a point on a number line?
