- 6. Each slice is a fraction of the pizza.<br />
- 7. Each segment is a fraction of the candy bar.<br />
- 8. Each brick is a fraction of the wall.<br />
- 9. We don’t always use the word “fraction”. Sometimes we just divide things.<br />
- 10. “Fraction” is the math word. But there are other words that mean the same thing:<br />A small piece<br />A slice<br />A little bit<br />Most of it<br />A share of<br />The lion’s share<br />A portion of<br />Leftovers and remainders<br />

- 16. Fractioning is breaking up or splitting up. To fraction something is to break it apart.<br />
- 17. It can be broken up even more.<br />
- 18. It can still be broken up again.<br />
- 19. Fractioning can occur many, many times. No matter the size, all the pieces are fractions.<br />
- 20. We use numbers to show the division. These fractions are mathematical expressions.<br />½<br /> ¾<br /> 5/8<br /> 10/16<br />5/4<br /> 999/1000<br />
- 21. Other words for fractions and whole:<br />Full- half full- empty<br />Percentages <br />Decimals<br />Unit and segments <br />
- 22. Coins are fractions of dollars.<br />
- 23. End of Part One<br />Cooperative group assignment: In your group, read about “Animal Clutches” on p. 218 in your Student Reference Book. <br />In journals, write three observations about animal clutches. Bring Reference Books and Journals to Math group.<br />In Math group, complete a parts-and-total chart using data from “Animal Clutches”.<br />Assessment: At your desk, complete Math Boxes in Student Math Journal, p. 36.<br />
- 24. Part Two: The Fractions<br />
- 25. Fractioning is breaking up a whole.<br />
- 26. Some fractional parts have names.<br />Half ½ Third 1/3 <br />Fourth ( or quarter) 1/4 <br />One fifth 1/5<br /> Three quarters 3/4 <br /> <br />
- 27. Money fractions have these names:<br />Cent or penny (1 ¢)<br />Nickel (5 ¢)<br />Dime (10 ¢)<br />Quarter (25 ¢)<br />Half Dollar (50 ¢)<br />
- 28. Remember: The fractions are equal parts of the whole.<br />
- 29. In math, we refer to the whole unit as an integer.<br />
- 30. Fractions are written like this. <br />The top number is the numerator.<br />The bottom number is the denominator.<br />⅚<br />
- 31. The denominator is downstairs.<br /> 9/10<br />Denominator<br />
- 32. The numerator is in the attic.<br />9/10<br />Numerator<br />
- 33. The fraction tells how many pieces of a whole unit we are dealing with.<br />5/6<br />2/3<br />
- 34. End of Part 2<br />Journaling activity: Use geometry blocks (2 colors)to construct fractional models. Refer to the instructions at the table.<br />Assessment: At your desk, write a paragraph in your journal about what your understanding of fractions.<br />
- 35. Part three: Fun Fraction Sites<br />
- 36. Here are some great sites for kids to learn more about fractions.<br />This was just the beginning. There is much more to learn about fractions. <br />These sites will help you to practice.<br />“What are Fractions?”<br />http://tinyurl.com/6glkx64<br />“Fraction Dominoes” http://tinyurl.com/6h38eh8<br />“Fractions” tutorial http://tinyurl.com/ax9wb<br />
- 37. More Fraction Sites for Kids<br />“Adding Fractions with Like Denominators” http://tinyurl.com/5tcntat<br />“Subtracting Fractions with Like Denominators” http://tinyurl.com/633rwp9<br />“Comparing Fractions” http://tinyurl.com/658wxd9<br />
- 38. More Fractions Sites for Kids<br />“Visual Fractions” http://www.visualfractions.com/<br />“Fresh Baked Fractions” http://tinyurl.com/8d54a<br />
