"I CAN"

I can identify parts of an expression including terms, constants, coefficients, and exponents.

An Algebraic Expression...

• Consist of one or more variables. Could also contain constants, variables or exponents separated by an operation 

   $\div$  ,+, -, x

• Does NOT have an equal sign.

• EX: 2x+3y+6 OR 5x OR a+b

Multiple Choice

What makes an Algebraic Expression?

• There are more than one operation(sign)

• There are variables

• There are only numbers

Multiple Choice

Which of the following is an algebraic Expression?

• 9+5

• 4s+7

• 2x+3=7

• b

Variable- a letter or symbol that represents an unknown quantity.

ex: b, r, x, j

Multiple Choice

What is the variable in the following expression?

9z +12

• 12

• 9

• +

• z

Coefficient- the number that is multiplied by the variable (the number in front of the variable)

9y - 8

9 is the coefficient

Term- Parts of an expression that are separated by a sign.

EX: 18y + 24 -17w

(3 terms)

Multiple Choice
