Day two of CMT Prep!

Tonight's homework is to complete strands 3 and 6.  They should go pretty well, but here are some pointers for strand three from MathIsFun:

Fractions, Decimals and Percents

Converting Decimals to Fractions

Converting Fractions to Decimals

Converting Decimals to Percents

Converting Fractions to Percents

Equivalent Fractions

Converting between Mixed Numbers and Improper Fractions

Good luck on tonight's HW!  Feel free to work on strands 10, 11, 12, 15 and/or 21 if you finish tonight's hw and have some time to do more work!

Dividing Fractions

Today we began dividing fractions.  If you felt good about multiplying fractions, you should have no trouble dividing as long as you remember to

KEEP IT!

CHANGE IT!

FLIP IT!

Watch the video below for some practice and extra information.

This video doesn't include cross cancelling, but the division steps are clear.  He also helps with simplifying and converting to mixed numbers.


Another video:  He flips, changes and keeps in the opposite direction but still only flips the second fraction.


Below, please find the steps and examples from class:

 Examples from the notesheet.  Not assigned for homework, but good to use for practice if you need more!

 Homework examples:

 ESTIMATE!!!!!!!!

Tonight's homework is to complete the dividing worksheet.  Good luck, work carefully!

Multiplying Fractions

As difficult as Adding and Subtracting Fractions are, Multiplying is just as EASY!!!

The steps for multiplying are:

The first step is to make everything a fraction.  If you have a whole number, convert it to an improper fraction by putting it over one.  If you have a mixed number, swirl around by multiplying the denominator by the whole number and adding the numerator to make the NEW numerator.  examples:

The next step is to cross cancel if you can.  Look for common factors on a diagonal to simplify BEFORE you multiply.  The examples below are problems after they have been cross cancelled, but before we multiply. 

After cross cancelling, multiply the numerators for a new numerator, multiply denominators for a new denominator.  The first examples are basic problems without cross cancelling, the second set include cross cancelling.

After getting your answer, make sure that you answer is in lowest terms.  If you cross cancelled, you should be there already, or at least pretty close to the final answer.  Some more examples from class:

This problem has two numbers that needed to be converted to fractions before we multiplied.  

 This examples includes one value that needed to be made improper and cross cancelling.

This problem wasn't too bad, but at the end, we needed to convert the improper fraction back into a mixed number.  We divided the numerator by the denominator to find the equivalent mixed number.

Are these problems getting easier? 

Two of the problems from tonight's homework are below.  Remember that the dot means multiplication.  Follow the steps on each problem:

• Make everything a Fraction
• Cross Cancel if you can
• Multiply Numerators
• Multiply Denominators
• Simplify if you can

Video Tutorials:

Could you have cross cancelled the second problem to make it a bit easier?

Tonight's homework is BOTH SIDES of the Multiplying Fractions Worksheet.  Good luck!

Mixed -> Improper -> Mixed -> Improper -> Mixed -> Improper

...and back again!

Tonight's homework is to complete worksheet 5-6, all problems!  Work carefully and do the awesome job I know you can do!!!

Converting between Improper fractions and Mixed numbers

Today we went over converting from Improper fractions to Mixed numbers and Mixed numbers to Improper fractions.  We also began reviewing adding and subtracting fractions towards the end of class.  Here are some screen shots from today's SmartBoard lesson to help you review or answer any questions that you may have!
