David after the Dentist/definitions.

hello, Its Devan

At the start of math class we watched "David after the dentist".

  • We talked about digital footprints.
  • We had a discussion about the internet safety, just remember-google never forgets.
  • Internet safety is a big deal. An example of this would be not to put your birthday, full name, phone numbers or anything like that.
  • Be careful what you put on the internet.
  • Ask yourself this question," If everybody I know saw this would it be okay?" That inculdes your parents, grandparents, friends etc. If you hessitate to answer this don't do it, cause it could come back to haunt you.
  • Math-Chapter 3- Pythagorean Relationship
  • Definitons
  • Prime Factorization- a number written as the product of its prime factor, the prime factorization of 6 is 2x3
  • Perfect square-a number that is the product of the same two factors, has only an even number of prime factors, 5x5=25, so 25 is a perfect square
  • Square root- a number that when multiplied by itself equals a given value, 6 is the square root of 36 because 6x6 = 36
  • Hypotenuse- the longest side of a right triangle, the side opposite the right angle
  • Pythagorean Relationship- the relationship between the lengths of the sides of a right triangle. The sum of the areas of the squares attached to the legs of a right triangle equals the area of the square attached to the hypotenuse.

  4. That's ok Devan! Thanks for trying. We'll have to discuss/research that tomorrow and the days to come. Once we find the way, maybe you can come back to this post and add it.

    By the way, do you think a space between "haunt you" and Ch. 3 Definitions might help the others be able to differentiate between the digital ethics part from the actual math part? Also, maybe putting the Ch. 3 part in all caps or something to show the break....(?)

    Also, let's change the label from David after...to digital footprint, ok.

    I know, I know, lots of revisions, but I wouldn't offer them if I didn't know you could do them.

    Way to go Dev!

  5. Gizzy, to add the map:

    Go to the links on the bottom left side of the blog and click on A Difference.

    Then, scroll down until you see Basic Tools. In this general area, you will see how to find the Visitor Map and some other cool gadgets as well.

    Good luck!
