Transcript

  • 1. Unit 7 Math Review
  • 2. What are Equivalent Fractions? • Fractions that are equal. The number of equal pieces are different, but the fraction’s value (out of the whole) is the same. • As an example, think of a two-slice pizza that has then been cut into four slices, six slices, etc. The size of the original pizza hasn’t changed!
  • 3. Find Equivalent Fractions • What is a fraction equal to 1/2 ? • What is a fraction equal to 2/5 ? • What is a fraction equal to 15/30 ?
  • 4. Comparing Fractions Which fraction is bigger? 6/7 or 3/5 How can you tell?
  • 5. Comparing Fractions continued Which fraction is bigger? 1/5 or 1/7 How can you tell?
  • 6. Ordering Fractions 75/100 1/2 11/12 Smallest 1/23 Largest 1/3 1
  • 7. Ordering Fractions 75/100 1/2 11/12 1 Smallest 1/23 Largest 1/3
  • 8. Ordering Fractions 75/100 1/2 11/12 1 Smallest 1/23 Largest 1/3
  • 9. Ordering Fractions 1/2 75/100 11/12 1 Smallest 1/23 Largest 1/3
  • 10. Ordering Fractions 1/2 75/100 11/12 1 Smallest 1/23 Largest 1/3
  • 11. Ordering Fractions 1/3 1/2 75/100 11/12 1 Smallest 1/23 Largest
  • 12. Ordering Fractions 1/23 1/3 1/2 75/100 11/12 1 Smallest Largest
  • 13. Finding the ONE (or the WHOLE)
  • 14. Finding the ONE (or the WHOLE)
  • 15. Finding the ONE (or the WHOLE)
  • 16. Fractions in Number Stories Courtney was tired of her collection of 12 teddy bears. She sold 3/4 of them at a yard sale. 9 How many teddy bears did she sell? 3 How many teddy bears does she have left?
  • 17. Probability A sack contains You reach into the sack and pull out a marble 4 red marbles without looking. About what fraction of the 3 green marbles time would you expect 2 black marbles to pull out a black marble? 5 white marbles 2/14 or 1/7
  • 18. Probability A sack contains What percent chance do you have of pulling out a 4 red marbles red marble? 3 green marbles (Use the calculator on your 2 black marbles widgets to help you!) 5 white marbles 4 / 14 x 100 = ? Answer: 28.5%
  • 19. Plotting Coordinate Points 10 9 Where would you plot (3, 3)? 8 Where would you plot (5, 7)? 7 6 Where would you plot (9, 0)? 5 4 Where would you plot (7, 10)? 3 2 1 1 2 3 4 5 6 7 8 9 10
  • 20. Which Fraction is Larger? 5/6 11/12 or 11/12 is bigger because it is only 1/12 away from being a whole. 5/6 is 1/6 away from being a whole. Twelfths are smaller pieces than sixths. In other words, 1/12 is smaller than 1/6, so 11/12 is the larger fraction.
  • 21. Making Spinners Color the spinner so that it will land on red about 50% of the time. Color the spinner so that it will land on blue about 1/4 of the time. What fraction and percent of the spinner is yellow? 1/4 or 25%
  • 22. Adding and Subtracting Fractions 1/5 + 2/5 = 3/5 3/7 6/7 - 3/7 = 1/6 + 1/3 = 3/6 or 1/2 COMMON DENOMINATOR! 2/3 - 1/4 = 5/12 COMMON DENOMINATOR!
  • 23. Good luck mathematicians. Happy studying!
