Spiral Review

Today we are going to spiral review through some of the topics we have learned this year.

Look through each slide and use this information or your math notebook to answer each question to the best of your ability.

Addition/Subtraction: Make sure to line up the decimals!!!!

Multiplying: Count how many numbers are behind the decimal point in both numbers to place your decimal!

Dividing: If your divisor has a decimal, you must move the decimal point in BOTH the dividend & divisor before dividing!

Step 1: Keep the first fraction the same

Step 2: Flip the second fraction upside down

Step 3: Multiply across

Step 4: Simplify!

Where you try to find the smallest multiple they have in common!

This is usually found by skip-counting until they find a match!

Where you try to find the largest/greatest number that divides evenly into both numbers

Can be found by listing the different factors.

How many times a number is multiplied by itself.

Example:

You can only combine terms with the SAME VARIABLE!!

Variable: a letter that represents a number

Constant: a number by itself

Coefficient: a number multiplied by a letter (example: 6y)

Use the inverse operation to find the answer to the equation or inequality.

The same is for inequalities!!

Example: 5y > 15

                   y > 3

Close Circle: ≥ or ≤

Open Circle: > or <
