Hurrah it's my post thanks Jo for switching it at the last minute.Its a day late but I'm still going to use the word today.

Okay today in class we made 2 foldables, yes 2, one was for the Real numbers, Natural, Whole, Integers, Rational, and Irrational numbers. I made the pictures in paint because it's too hard to take the pictures. The first image is the front and second page and the second is the inside of the 1st foldable. We basically just put what is in the set, what numbers go in each category, the numbers that don't belong in each set, and numbers we don't usually think of. For homework with this we were supposed to finish all the things we didn't do and add the definitions.

This lovely little picture here is the second foldable, well half of it at least. Mr. Backe explained how to multiply improper fractions, proper, and mixed numbers, and how to divided them as well.
The homework for this was to make 10 questions each for dividing and multiplying using the way he showed us.

Yeah yeah I know its not great but I'm me what did you expect. If you didn't understand something or I missed something leave a comment.
Oh yeah and as I said already today Josh, your doing the next one.

Connor's Blogpost for October 18

In Mr. Backe's math class today we started off with playing a new decimal version of our previous card game.

The operation used was addition. The game basically worked by all red cards were negative decimals, black cards were positive numbers and the face cards were 0.9 and its opposite. The cards were very simple because they were only decimals in the tenths place value and between
-1, 0, 1.

Then we continued on with making a new foldable.
We started 1/3 down the horizantal page with this image below.





















If you cannot read this diagram, this is a list of what it says;
-Natural Numbers and Counting Numbers
Eg. 1,2,3,4,5,6,7,8,9
-Whole Numbers
Eg. All Natural numbers and 0
-Integers
Eg. All Numbers and the opposites
-Rational Number
Eg. All numbers that can be expressed in a/b, where a and b are integers but b cannot = 0
-Irrational Numbers
Eg. None terminating numbers, none repeating numbers, decimal numbers like Pi and square roots of none perfect squares.
-Real Numbers
Eg. All numbers in the chart excluding imaginary numbers.

The initials for the categories are;
Natural Numbers = N
Whole Numbers = W
Integers = I
Rational Numbers = Q
Irrational Numbers = Q' <--- The tick on the top right corner of the Q means prime.
Real Numbers = R

The Boxes represent that every smaller box inside the bigger box, fits under the bigger boxes category. For example Natural Numbers and Whole numbers fit under the Integers box. And all the boxes including Irractional numbers fit under the real numbers category.

This is as far as we have gotten on the foldable in todays math class.
Homework for tonight is;
Play tutpup
Decimal Booklet
2.1 Extra Practice
Text Book 2.1 Practice, Apply and Extend
Also if you havn't finished the above image on your foldable, complete that too.
