# Sixth Grade On Level Math

## From Mrs. Ruelas:

This review will guide you to be more successful on the semester exam. Anchor charts and guides are posted below.

## Topics for Review:

**Comparing fractions****Putting decimals in order from least to greatest, etc.****Adding and subtracting fractions****Finding the ratio of a selected group****Changing fractions into decimals and percents****Least Common Multiple****Greatest Common Factor****Order of Operations****Prime Factorization****Improper Fractions and Mixed Numbers**

## Anchor Charts

## Improper fractionsConverting improper fractions to mixed numbers. | ## Making percentsMaking percents from fractions. If you can't make an equivalent fraction where the denominator is 10 or 100, you have to divide! (step 4) | ## Adding fractionsNever add the denominator! When your denominators are the same, you can add the numerator. Don't forget to simplify! |

## Making percents

Making percents from fractions. If you can't make an equivalent fraction where the denominator is 10 or 100, you have to divide! (step 4)

## Mixed Numbers to improper FractionsMultiply your denominator by your whole number. Add this to your numerator. This number is your new numerator; the denominator stays the same. | ## Word Wall | ## Adding and Subtracting FractionsThe key is to make sure your denominators are the same! You cannot add or subtract fractions, or compare them unless your denominators are the same. |

## Mixed Numbers to improper Fractions

Multiply your denominator by your whole number.

Add this to your numerator.

This number is your new numerator; the denominator stays the same.

## Converting Decimals to FractionsRemember your decimal place values!
| ## Prime FactorizationMake sure all your numbers in your final equation are PRIME. | ## Greatest Common FactorRemember, factors are |

## Order of OperationsMultiplication and division are equal, solve them from left to right; Addition and subtraction are equal, solve them from left to right. | ## Converting Fractions to DecimalsYour denominator has to be a 10 or 100 or 1000 to write the fraction as a decimal. If you cannot make this happen, you will need to divide, which is step 4. | ## Least Common Multiple |

## Order of Operations

Multiplication and division are equal, solve them from left to right;

Addition and subtraction are equal, solve them from left to right.

## Converting Fractions to Decimals

Your denominator has to be a 10 or 100 or 1000 to write the fraction as a decimal.

If you cannot make this happen, you will need to divide, which is step 4.
