  12. What’s the Difference? 0.8 80%

  13. What’s the Difference? 0.8 80%

  14. Decimals • Decimal – A fractional amount based around powers of 10 (tenths, hundredths, thousandths). Why use them?

  15. Which is more? 3.6 pounds of hot chips 3.75 pounds of hot chips

  16. Which is more? 3 pounds of hot chips 3 pounds of hot chips

  17. Decimals • Decimal – A fractional amount based around powers of 10 (tenths, hundredths, thousandths). Why use them? Decimals let us recognize the value of a fractional number quickly.

  18. Decimals • Decimal – A fractional amount based around powers of 10 (tenths, hundredths, thousandths). Why use them? Decimals let us recognize the value of a fractional number quickly. Calculating with decimals is very similar to calculating with whole numbers.

  19. Fraction • Fraction – Used to represent any part of a whole. Why use them?

  20. More parts of a whole!

  21. More parts of a whole!

  22. More parts of a whole! 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1

  23. Fraction • Fraction – Used to represent any part of a whole. Why use them? Fractions don’t need to be based around powers of 10.

  24. Fraction • Fraction – Used to represent any part of a whole. Why use them? Fractions don’t need to be based around powers of 10. Better for small, quick divisions of whole amounts

  25. Percent • Percent – A part of a whole where the whole is always 100. Why use them?

  26. Who did better? • Jennifer received an 8 out of 10 on a quiz in math. She received a 17 out of 20 on a quiz in science. Which quiz did she do better in?

  27. Who did better? • Jennifer received an 8 out of 10 on a quiz in math. She received a 17 out of 20 on a quiz in science. Which quiz did she do better in? 80% 85%

  28. Percent • Percent – A part of a whole where the whole is always 100. Why use them? Percentages allow us to compare any fractional amount quickly.

  29. Switch it around! 80% = = 0.80

  30. Percent • Percent – A part of a whole where the whole is always 100. Why use them? Percentages allow us to compare any fractional amount quickly. Percentages can quickly be turned into fractions OR decimals.

  31. Who did better? • Jennifer received an 8 out of 10 on a quiz in math. She received a 17 out of 20 on a quiz in science. Which quiz did she do better in? 80% 85%

  32. Percent • Percent – A part of a whole where the whole is always 100. Why use them? Percentages allow us to compare any fractional amount quickly. Percentages can quickly be turned into fractions OR decimals. Percentages do a good job of telling us how close a value is to one whole (100%).

  33. Decimal, Fraction, Percent? • Kasey wants to give 3 out of her 7 pieces of Starburst to her friends. What would you use to represent this amount?

  34. Decimal, Fraction, Percent? • Kasey wants to give 3 out of her 7 pieces of Starburst to her friends. What would you use to represent this amount? • Use a fraction () because it is a quick division that doesn’t involve the number 10.

  35. Decimal, Fraction, Percent? • Damarkusearned 12 points correct out of a 15 question test, and he wants to know how well that compares to his other grades. What would he use?

  36. Decimal, Fraction, Percent? • Damarkus earned 12 points correct out of a 15 question test, and he wants to know how well that compares to his other grades. What would he use? • Use a percentage (80%) because he can then easily see how well his score compares to other grades.

  37. Work It – partner Time • Ms. Lonsdale sees that Apples are on sale for just 22 cents each. If she wants to see how much 6 apples will cost her, what should she use? • A recent survey shows that 3 out of 5 students prefer the color blue. If you wanted to see how close that was to having all students preferring blue, what would you use? • Ms. Jackson is measuring ingredients to make corn bread, and knows that she has to fill her measuring cup up to the third measuring line out of a total of 4 measuring lines.
