  1. FUN WITH FRACTIONS! A Study Guide and Review Game

  2. What is a fraction? • A symbol that is used to name equal parts of a whole. • A fraction has a NUMERATOR. • The numerator is the top number and it names the part that is shaded or unshaded. • A fraction has a DENOMINATOR • The denominator is the bottom number and it names the total number of pieces in the whole.

  3. Here’s a Hint… 24 The number in the NORTH is the Numerator! The number that is DOWN is the Denominator!

  4. Part of a whole 3 is yellow 8

  5. Part of a set 4of the set are pears5

  6. Position on a number line

  7. Naming Parts of a Whole

  8. Naming Fractional Parts

  9. Finding Equivalent Fractions • EQUivALent means EQUAL! • 3 is EQUivALent to 16 2

  10. Here’s a Hint… • To find equivalent fractions…LOOK FOR A PATTERN 12345 2 4 6 8 10

  11. Here’s Another Hint… • To find equivalent fractions…USE BOTTOMS UP! 24 24 34 6 8 =

  12. Comparing Fractions…Use Bottoms Up! 16 6 21 6 8 > Two-sixths is greater than one-eighth

  13. Comparing Fractions…Use Bottoms Up! 15 24 52 12 3 < Five-twelfths is less than two-thirds

  14. Ordering Fractions • You will be asked to order fractions from Greatest to Leastand from Least to Greatest • You have three strategies to choose from: • Draw a picture • Use Bottoms Up • Use Fraction Fringe

  15. Ordering Fractions withDrawing A Picture 111 3 6 9 Least to greatest:    111 9 6 3

  16. 11 3 6 > 11 3 9 11 6 9 > > Ordering Fractions with Bottoms Up 111 3 6 9 • Compare 1 and 1 3 6 • Compare 1 and 1 3 9 • Compare 1 and 1 6 9 Since 1/3 was largest 2 times, it is the largest fraction! 1/6 is next, followed by 1/9.

  17. Ordering Fractions with Fraction Fringe (you can draw it!)

  18. Finding Parts of a Set When a picture is given, put the items into groups based on the number in the denominator. 1 of 9 books = 3books in each group 3

  19. Finding Parts of a Set When a picture is not given, you have two choices: • Draw a picture and solve! • Do the math!

  20. = x 8 times what = 64? 1Of 64 = 8 ?

  21. Mixed Numbers • A mixed number is a whole number and a fraction combined

  22. Mixed Numbers • Count the WHOLEs first • Then find the FRACTIONal part

  23. Fraction Problem Solving • USE YOUR STRATEGIES!!! Do not try to work out the problems in your head !!! • Review all of the tricks and hints in this slideshow! • Review your notes from class! • PRACTICE! PRACTICE! PRACTICE!

  24. Why do I need to know this stuff? • Fractions can and will help you in real life. In order to figure out how to make only part of a recipe because you do not want to feed ten people, but only five, fractions will be very helpful. • You can use fractions to divide cake, or candy, and you will need fractions to help figure out percents. • Fractions are useful when you buy paint to make your house look nice and for figuring how much interest you will pay to the bank when you take a loan. • Fractions may be a bit difficult to learn, but believe me, you will be happy that you spent the time.
