Real Numbers: Activity - Application of Negative Numbers

4 comments:

  1. @Mac Spicy:

    1. For temperature, quote real world example: http://news.bbc.co.uk/weather/forecast/107?&search=chicago&itemsPerPage=10&region=world
    The hyperlink links to a Lesson Plan website that illustrates how the concept of negative numbers could be taught. It doesn't illustrate "negative number" in application.

    2. Electronic Calculator:
    Are you able to illustrate with a photograph (capture it using iSight)

    3. Graphs:
    Insert a image, or provide a website to show an example of graph with negative numbers

    4. Spending Money:
    In what way, elaborate. Or is it reported 'somewhere'? Give the website.

    1. Elevation example [1]

    2. Latitude & Longitude
    - Provide a diagram or an explanation from an authorised website that illustrates the use of negative number when reporting on latitude/ longitude.

    3. Temperature
    Quote a real world example (e.g. http://news.bbc.co.uk/weather/forecast/107?&search=chicago&itemsPerPage=10&region=world)

    4. The use in Finance
    Given an example or include a site by an organisation that uses negative number to report on its figures.

    5. Use in Sports
    The hyperlink given links to a resource/ lesson website (that is created to teach what negative numbers mean). It does not show how it's used in Sports.
    A link to a Sports website or a photo to show the scoreboard that illustrates negative number in use would be relevant.

    6. About Floods
    It would be clearer if there's a diagram/ image to illustrate

    7. Buildings
    Give an image to illustrate how negative numbers are in use within buildings

    1. Elevation at Sea level [1]

    2. Engineering Tolerance
    Provide an website where negative number is put to use in this field. The wikipedia site only attempts to explain what it is and cite examples of how it is being used in real world.

    3. Velocity example
    The link doesn't work.

    4. Calculator example
    The link doesn't work.

    5. Profits and losses in the working world
    The page did not show any illustration on negative numbers in use. (not explicit)

    6. Temperature
    Quote a real world example (e.g. http://news.bbc.co.uk/weather/forecast/107?&search=chicago&itemsPerPage=10&region=world). The wikipedia site only attempts to explain what it is and cite examples of how it is being used in real world.

    7. Stock Market
    The picture doesn't tell the use of negative numbers. Provide a hyperlink to a relevant website where you could see graphs with negative numbers/ axis.

    8. G-force
    The wikipedia site only attempts to explain what it is and cite examples of how it is being used in real world.

    9. Overdraft in finance/banking
    The use of negative number is not explicitly explained in the website. A more appropriate site could be a website of a bank that provides examples or illustrations to its customers.

    2. Negative Altitude
    Quote an example from a website of an organisation/ agency that does work that deals with negative altitude (e.g. research on ocean creatures)

    3. Golf Score card
    Is there any image for illustration?

    4. Velocity [1]

    for the rest of the examples cited, need to give concrete/ explicit illustrations.
