Presentation Transcript

  1. How do you compare fractions with different numerators and denominators to a benchmark fraction by using number lines? For example: 1 .3 1 .2 4 . 6

  2. In this lesson, you will learn how to compare fractions with different numerators and denominators to the benchmark fraction of by using number lines. 1 .2

  3. Let’s Review Denominator: How many equal parts make up a whole Let’s Review Numerator: How many parts you have 1. 2

  4. Let’s Review There are 3 signs needed to compare fractions. Let’s Review < = >

  5. A Common Mistake Comparing the numerators without looking at the denominators. Let’s Review 2 . 3 2 . 4

  6. A Common Mistake Failing to divide the number line into equal parts based on the fraction denominator. Let’s Review 8 .8 3 .8 3 .8 4 .8 2 .8 7 .8 1 .8 5 .8 6 .8 0 1

  7. Core Lesson 1.2 1.2 0 1 3.8 1 .8 2 .8 3 .8 4 .8 7 .8 5 .8 6 .8 0 1 1.2 3.8 >

  8. Core Lesson to the benchmark fraction ? and How could you use number lines to compare the fractions 1 .3 4 .6 1 .2 1.3 2.3 1.3 0 1 1.2 1.2 0 1 4. 6 2.6 5.6 4.6 3.6 1.6 0 1 1.3 1.2 4. 6 < <

  9. In this lesson, you learned how to compare fractions with different numerators and denominators to the benchmark fraction by using number lines. 1 .2

  10. Guided Practice Use the number lines below to compare the fractions. Let’s Review 1.6 0 1 1.2 0 1 5.12 0 1

  11. Extension Activity Let’s Review Use number lines to order the fractions from smallest to largest. 1.2 3.6 2.5

  12. Extension Activity Let’s Review What would be another way to compare fractions, other than using number lines?

  13. Extension Activity Let’s Review Ordering Fractions Each student needs a set of fraction blocks to help them during the game. The teacher begins by writing 12 fractions on large index cards (1 fraction per card), and telling students it is there job to put the fractions in order from least to greatest. Write a number line on the board for students to see. Show the cards one at a time to the students, while asking them where it belongs on the line. When the students answer correctly, place the card in the appropriate place on the board.

  14. Extension Activity Let’s Review Draw a stack of 3 number lines on your paper. Each number line should have the points 0 and 1 on it. On the top number line, figure out where 1/12 is. On the next one, chart 1/6. On the third line, find 1/3. What do you notice about the pattern? Now draw a fourth line and find 1/2. How does this line compare to the others?

  15. Quick Quiz Let’s Review Use number lines to find the fraction less than . 1 .2 1 .6 A. 0 1 0 1 4 .9 B. 0 1 0 1 3 .4 C. 5 .10 D.

  16. Quick Quiz Let’s Review Use number lines to find the fraction greater than . 1 .2 2 .16 A. 0 1 0 1 1 .4 B. 0 1 0 1 3 .4 C. 4 .8 D.
