Do you measure up?

  1. 1. Do you measure up?<br />By:<br />Cassaundra Hisch<br />
  2. 2. Standard 5: The Mathematical World<br />Numbers: 3.5.1 Select and use appropriate measuring units, such as centimeters (cm) and meters (m), grams (g) and kilograms (kg), and degrees Celsius (°C).<br />Activity modeled after<br />
  3. 3. Definitions<br />Appropriate: Suitable for a particular condition, occasion, or place; fitting.<br />Measurement: The dimension, quantity, or capacity determined by measuring<br />Units: What the measurement is being done in, (example: inches)<br />
  4. 4. Background Info<br />Knowing when to use measurements appropriately is important.<br />Here we will explore the importance of measurements and how to use them properly.<br />
  5. 5. What’s missing from these sentences?<br />The worm is 3 long.<br />Katie’s plant grew 11 tall.<br />The school is 22 tall.<br />Yesterday it was 34 outside.<br />
  6. 6. Did you figure it out?<br />Measurements are what is missing!<br />Why do we need measurements?<br />Did those sentences make sense without measurements?<br />
  7. 7. Much Better!<br />These sentences make a lot more sense when we add in measurements!<br />The worm is 3 inches long.<br />Katie’s plant grew 11 centimeters tall.<br />The school is 22 feet tall.<br />Yesterday it was 34° outside.<br />
  8. 8. How do we know?<br />You know measurements are important…<br />Now you may be wondering: How do I know what measurements to use?<br />Make a list of all the measurements you know how to use…<br />
  9. 9. Measurements I Know<br />_____________________________________________<br />_____________________________________________<br />_____________________________________________<br />_____________________________________________<br />_____________________________________________<br />_____________________________________________<br />
  10. 10. Let’s compare our lists…<br />Centimeters (cm)<br />Meters (m) <br />Inches (in) <br />Feet (ft)<br />Yards (yd)<br />Millimeters (mm)<br />Miles (mi)<br />Kilometers (km)<br />Pounds (lbs)<br />Grams (g)<br />Milligrams (mg)<br />Tons (T)<br />
  11. 11. Let’s get started!<br />Those were just some examples of measurements you may know how to use. There may be more.<br />With all of those how do you know when to use which one?<br />
  12. 12. Length<br />Units for measuring in lengths include: millimeters, centimeters, inches, meters, feet, yards, miles, and kilometers.<br />Units in yellow are good for small measurements.<br />Units in blue are good for medium measurements.<br />Units in purple are used for long distances.<br />
  13. 13. Medium Measurements<br />Feet, yards, and meters are used to measure things that aren’t big or small. Inches are also used in some cases.<br />Examples are:<br />The length of a car<br />The height of a tree<br />The length of a sports field<br />
  14. 14. Small Measurements <br />Remember we commonly use millimeters, centimeters, and inches for these.<br />Example measurements include:<br />The width of a fingernail<br />The size of a pebble<br />The length of a pencil<br />
  15. 15. Long Measurements<br />Miles and kilometers are commonly used for measuring long distances.<br />Examples of long measurements include:<br />Length of a trip<br />Length of a road<br />
  16. 16. Example <br />
  17. 17. Weight Measurements <br />Small weights are measured using milligrams or grams. (examples: the weight of a dime or pencil)<br />Medium weights are measured using pounds or kilograms. (examples: the weight of a person or animal)<br />Things that are heavy are usually measured in tons. (examples: trucks and cars)<br />
  18. 18. Let’s Practice<br />You have a penny. What measurements should you use to find its:<br />Weight?<br />Height? (edge)<br />Diameter?<br />
  19. 19. Answers<br />Weight- measure weight in grams or milligrams<br />Edge height- millimeters would work best for this <br />Diameter- centimeters or inches would make the most sense here.<br />
  20. 20. In the bag you should find…<br />A worksheet<br />Various items<br />Rulers<br />Follow the directions on the worksheet!<br />
  21. 21. Assessment<br />1. What measurement is appropriate for measuring the length of a pencil?<br />A. Yards<br />B. Pounds<br />C. Feet<br />D. Centimeters<br />
  22. 22. Assessment<br />2. If I am wanting to weigh my dog, what measurement should I use?<br />A. Kilograms<br />B. Tons<br />C. Yards<br />D. Milligrams<br />
  23. 23. Assessment<br />3. Which of the following would be best measured in yards?<br />A. The length of a shoe<br />B. The weight of your backpack<br />C. The length of a basketball court<br />D. The length of your thumb<br />
