Patterns And Expressions

Patterns- Are arrangements of shapes, colours, letters, numbers, etc. For which you can predict what comes next

Constant- A number that does not change. Increases or decreases the value of the expression no matter what the value of the variable
Example: 2x+4, 4 is the constant

Variable- A letter that represents an unknown number
Example: 2x+4, x is the variable

Numerical Coefficient- A number that multiplies the variable
Example: 2x+4, 2 is the numerical coefficient

Expression- Any single number or variable, or a combination of operations involving numbers and variables
Example: 2y-7, 11x, and 14 are expressions

Equation- Mathematical statement with two expressions that have the same value
Example: x+2=3, y-7=(-4)

Value- A known or calculated amount

Linear Relation- A pattern made by two sets of numbers that results in points along a straight line on a coordinate grid

Graph- A visual way to show how two sets of numbers relate to each other

Relationship- A pattern formed by two sets of numbers

Hi Casey,Good Job on your post!I liked how you put the words in different colors and the definition in another. I also liked how you put the examples in red it really catches attention. You also forgot to add a link but sorry, I couldn't find one to suggest.

Hey Casey, Well done! I like how you change the color of the font, it makes it really attractive. The definitions really help me a lot! It would also be great if you the font size and add a picture. Here is an example to put: http://1.bp.blogspot.com/-0QnT9GYn8uU/TeRaqMBWvCI/AAAAAAAAAUM/T0Z5Ycr1m1c/s400/SHAPES9.png

Hi Casey, great scribe post. I like how you added some color on some words so that we can see better but I think you could of added a bit more. I suggest you try making the font for bigger so that it catches the readers attention. I also suggest you try adding some pictures to make it stand out more. Good job Casey :)
