Slide 1: Fraction Finder Can you identify the fractions? Can you identify the parts of a fraction? Slide 2: What is a fraction? Fractions are parts of a whole. If an amount is divided into equal parts, or fair shares, we can understand and name the fractions. A fraction is the top number (called the numerator) divided by the bottom number (called the denominator). Slide 3: Some examples of fractions: A graphical example of fraction 1/3 is shown by the pie chart below. The pie is divided into 3 equal parts. The blue part is equal to one third of the pie, thus 1/3. A graphical example of fraction 7/8 is shown by the apples below. A box holds 8 apples. One apple is missing from the box. There are 7 apples left in the box, thus 7/8. Some examples of fractions: 1/3 2/5 7/8 A graphical example of fraction 1/3 is shown by the pie chart below. The pie is divided into 3 equal parts. The blue part is equal to one third of the pie, thus 1/3. A graphical example of fraction 2/5 is shown by the marching men below. There are five marching men in the illustration. There are 2 men in orange uniform, thus 2/5. A graphical example of fraction 7/8 is shown by the apples below. A box holds 8 apples. One apple is missing from the box. There are 7 apples left in the box, thus 7/8. Slide 4: 3 Questions to Ask: 1. What is the whole and how big is it? * All wholes are not the same. * 1/2 of $10.00 is not the same as 1/2 of $100.00. 1/2 = $5.00 1/2 = $50.00 Slide 5: 2. Into how many equal parts has the whole been divided? * If the whole has been divided into equal parts, we can understand and name the fractions, and the number of parts tells us what fraction of the whole each part is. * The denominator tells us what fraction of the whole each part is. If an 8 inch pie is divided into 4 equal parts, the denominator is 4, and each slice is ¼ of the pie. Slide 6: 3. How many of the equal parts are we using? * This tells us the actual amount of the whole that is being dealt with. * The numerator of a fraction tells us how many of the equal parts we are using. If we ate 1 piece of the 8 inch pie that was divided into 4 equal pieces, the numerator is 1, and we would have eaten ¼ of the pie. Slide 7: Do You Really Know What The Questions Mean? For Example: 1. ½ the class tells us that there are two equal parts and we are using one of the parts. Do we know the size of the whole class? 2. 2 pieces of cake tells us we are using 2 of the pieces. Do we know how many pieces there are in all, or if they are equal? 3. ¼ of a dollar tells us the whole is $1.00, it is divided into 4 equal parts of $0.25 each, and we are using 1 of the parts, or $0.25. We can answer all three questions about this amount, so we really understand what it means. Slide 8: Can you answer the 3 questions? What is the whole? 4/4 How many parts? 4 How many parts are we using? 1 Slide 9: What fraction of this shape is yellow? 1 4 What is the numerator? 1 What is the denominator? 4 Slide 10: Can you answer the 3 questions? What is the whole? 9/9 How many parts? 9 How many parts are we using? 4 Slide 11: What fraction of this shape is yellow? 4 9 What is the numerator? 4 What is the denominator? 9 Slide 12: Can you answer the 3 questions? What is the whole? 2/2 How many parts? 2 How many parts are we using? 1 Slide 13: What fraction of this shape is yellow? 1 2 What is the numerator? 1 What is the denominator? 2 Slide 14: Can you answer the 3 questions? What is the whole? 6/6 How many parts? 6 How many parts are we using? 3 Slide 15: What fraction of this shape is yellow? 3 6 1 2 or What is the numerator? 3 or 1 What is the denominator? 6 or 2 Slide 16: What fraction of this shape is blue? 2 6 What is the numerator? 2 What is the denominator? 6 Slide 17: What fraction of this shape is pink? 6 12 or 1 2 What is the numerator? 6 or 1 What is the denominator? 12 or 2 Slide 18: What fraction of this shape is purple? 1 6 What is the numerator? 1 What is the denominator? 6 Slide 19: What fraction of this shape is green? 4 4 or 1 whole What is the numerator? 4 What is the denominator? 4 Or it is 1 whole Slide 20: Can you identify the fraction? x x x 3/6 or 1/2 x x 2/5 x 1/3 x x x 3/4 Slide 21: Let's Practice Some More! How much pizza is left? Slide 22: How much pizza is left? Slide 23: How much pizza is left? Slide 24: How much pizza is left? Slide 25: What fraction of the design is blue?
