Proportions n measurement

  1. 1. + Using Proportions to Convert Measurements Ms. Johnson 8th Grade Math
  2. 2. + Systems of Measurement  DoNow: Write down as many words as you can that you associate with measurement Quote of the day: “Action is the real measure of intelligence.” -Napoleon Hill
  3. 3. + Systems of Measurement
  4. 4. +  We measure all sorts of quantities. Here are the main ones:
  5. 5. + Systems of Measurement  There are two categories we can place the words you just saw in. These two categories are called the two systems of measurement METRIC and CUSTOMARY/STANDARD
  6. 6. + Systems of Measurement  There are two categories we can place the words you just saw in. These two categories are called the two systems of measurement Quantity METRIC and CUSTOMARY/ STANDARD Length meter inch, yard, foot, mile Volume liter gallon, quart, pint, hogshead Mass/Weight gram pound, ounce Temperature Celsius Fahrenheit
  7. 7. + Systems of Measurement  Ifyou notice, there are a lot of words for each customary/standard measurement.  The world is turning to all metric and soon these will be the only ones we need! Quantity METRIC and CUSTOMARY/ STANDARD Length meter inch, yard, foot, mile Volume liter gallon, quart, pint, hogshead Mass/Weight gram pound, ounce Temperature Celsius Fahrenheit
  8. 8. + Systems of Measurement  But how does the metric system work if they use so many less words than we do?? Quantity METRIC and CUSTOMARY/ STANDARD Length meter inch, yard, foot, mile Volume liter gallon, quart, pint, hogshead Mass/Weight gram pound, ounce Temperature Celsius Fahrenheit
  9. 9. + Systems of Measurement  Because they use prefixes to explain smaller and larger units!! Such as: milli, centi, deci, kilo Quantity METRIC and CUSTOMARY/ STANDARD Length meter inch, yard, foot, mile Volume liter gallon, quart, pint, hogshead Mass/Weight gram pound, ounce Temperature Celsius Fahrenheit
  10. 10. + Systems of Measurement  Prefixes for Metric System SMALLER BIGGER milli (1/1000) ,centi (1/100), deci (1/10), kilo (1000) Quantity METRIC and CUSTOMARY/ STANDARD Length meter inch, yard, foot, mile Volume liter gallon, quart, pint, hogshead Mass/Weight gram pound, ounce Temperature Celsius Fahrenheit
  11. 11. + Systems of Measurement  Fun side note: This is the ipod nano j N Nano- is another funny metric prefix. Nano- 10-9 j 1 Billionth … REALLY tiny ! TINY
  12. 12. + Review of Proportions  Proportion: 2 ratios that are equal to each other ex) 2:6 :: 3: 9 aka 2 =3 6 9
  13. 13. + Review of Proportions  Proportion: 2 ratios that are equal to each other ex) 2:6 :: 3: 9 aka 2 =3 6 9
