  1. FRACTIONS

  2. Let’s draw a rectangle, and divide it in two equal parts...

  3. The red part of the rectanglerepresents a fraction… 1/2 (one half)

  4. Now, let’s draw a circle and divide it in two equal parts...

  5. The red part of the circlerepresents a fraction… 1/2 (one half)

  6. Very Good!!! Now let’s draw another rectangle and divide it in three equal parts...

  7. Thered part of the rectanglerepresents another fraction… 1/3 (one third)

  8. Very Good!!! Now let’s draw a circle and divide it in 4 equal parts...

  9. The red part of the circlerepresents a fraction… 1/4 (one fourth)

  10. Very Good!!! Now you know what a Fraction is!!! Remember that in a fraction the number below the line indicates the total number of equal parts in which an object is divided…

  11. and the numberabove the line indicates the number of parts“selected” in that object...

  12. So, you can represent different fractions with the same object … For example, look at the following object...

  13. Now see how this rectangle can be used to showdifferent fractions….

  14. If we “select” 1 part of this rectangle, What is the fraction?

  15. If we “select” 1 part of this rectangle, What is the fraction? 1 ----- 4

  16. If we “select” 2 parts of this rectangle, what is the fraction?

  17. If we “select” 2 parts of this rectangle, what is the fraction? 2 ------- 4

  18. If we “select” 3 parts of this object, what is the fraction?

  19. If we “select” 3 parts of this object, what is the fraction? 3 ------- 4
