Today in math we did number of the day which was 1936.295. Number of the day is always homework! We had homework and notes:

Area= Area is the number of square units in a two dimensional region.

eg: 4 cm squared
4- amount cm- units

Area of rectangle or square

Length x width = area

a=L x W
a=6 x 2
a= 12 m squared

eg:

Parallelogram= a four sided figure with opposite sides parallel and equal in legth.

I means sides are equal in length
II
^ means lines are parallel

base= a side of a two dimensional closed figure
=common symbol is b.

height= the perpendicular distance from the base to the opposite side.
=common symbol is h.
eg:


Perpendicular= a line that meets another line at a right or 90 degree angle.

a= L x W a= b x h
a= 6 x 2 a= 6 x 3

a= 12 m squared a= 12 m squared

EEach height is the exact same size.

Area of Parallelogram

a= b x h

h= 3 cm a= b xh

b= 9 cm a= 9 x 3
a= 27 cm squared

Find the area of the following figures.

A:

Please comment me and tell me if I did any mistakes!!!

Today in math class we went to the computer lab and worked on our TLE. Today's lesson in TLE was ORDERING NUMBERS.

Today's objecive was: In this lesson you will learn to compare and order fractions, mixed numbers, and decimals.

-To do number 1 you have to write the method for ordering/comparing fractions with the same denominator. Example: 4/7 > 3/7
-To do number 2 you need to write the methods for ordering/comparing fractions with different numerators and denominators. Example: Which is greater, 3/5 or 4/9?

You need to change the denominator to 45 because it is the LCD of 5 and 9. Then just compare the numerator. There for the answer to this question is 4/9.

-Next you are going to do a vocabulary list which you can find on the glossary.

-In question number 1 in the other page, you need to use the <> symbol to complete the statement.

-Question number 2 is like number three but you need to change the denominator and replace it with the LCD. Which is 63 in this question. Then all you have to do is compare the numerator and write the correct symbol.

-The last question is just to write the following numbers from greatest to least.

Please comment the mistakes that I did. I choose Allen for the next scribe.
