2. I can write an algebraic expressions.
1.1 Using variables in expressions
1.2 Exponents & Order of Operations
I can write an algebraic expressions.
I can simplify numerical expressions using order of operations.
I can evaluate expressions.
I can define a variable and write an expression/equation.
Don’t forget to write this “I Can” in your target sheet.
(Bold words above are to signal those words were listed as an objective on the pre-test)

3. Variable - A symbol that represents one or more numbers.
1.1 Using variables in expressions
1.2 Exponents & Order of Operations
Variable - A symbol that represents one or more numbers.
Algebraic Expression - A mathematical phrase that can include numbers, variables, and operation symbols.

4. Ex 1. Write the following algebraic expressions in words: a.) h + 7
b.) 6 – p
c.) 5d + 2
i.e. The sum of h and seven
i.e. p less than six
i.e. the sum of two and the product of five and d
Ex 2. Define the variables and write an equation for the following:
a.) total income from selling tickets to a school play for $5 each
b.) the total cost is a number of packages of gum times $0.30
c.) the volume of a rectangular box is the product of length, width, and height.
i.e. T = total income
n = number of tickets
T = 5n
i.e. T = total cost
n = number of packages
T = 0.30n
i.e. V = volume
l = length
w = width
h = height
V = lwh

5. Simplify - put a numerical expression in its simplest form.
Exponent - tells you how many times a number is multiplied by itself.
Base - the number that is the factor. (the bottom #)
Power - the combination of a base and exponent.

9. Evaluate - substituting a given number for each variable and then using the order of operations to simplify.
for a=7 and b=4.
