More with Factor Trees, LCM and GCF!

We were really busy in class today, but we accomplished a lot!!!

We reviewed last night's homework, tried a challenge problem, worked on GCF and LCM word problems and some of us even got to play a LCM game online!

Take a look at the problems and work from class below and then try the snowball game yourself!

Snowball game:

Tonight's homework is to complete both sides of the prime, composite and factorization worksheet.  Numbers 1-9 should just be identifying if the number is prime (only factors are one and itself) or composite (more factors than just one and itself.)  Numbers 10-19 are factor trees just like the examples above and number 20 is like a factor tree in reverse.  I gave you the factorization, use those numbers to figure out what the original number was!

Tomorrow we will spend a bit of time working on factorization, LCM and GCF, but then we will begin multiplying and dividing fractions!  (It sounds scarier than it actually is!)

Greatest Common Factor

We use Prime Factorization to help us determine the Greatest Common Factor of two or more numbers.

First Prime Factorization from "Bob"



Now, use it to find GCF:



Notes from class:

Tonight's homework is to complete both sides of the Factor Tree and GCF worksheet.  Feel free to use your orange paper to help you!

LCM

Least Common Multiple

Tonight's homework is to complete worksheet 5-3.  You must do numbers 1-8 and both 53 and 54.  You may pick 20 problems between #'s 9-52.

Do all and remember that each problem requires three answers.

 Choose 20 of the following 44 questions.

53.  Miss K works Monday through Saturday, so she has a day off once every 7 days.  She calls Missy in California every 5 days.  How often does she get to call Missy on her day off?

54.  The traffic signal near Starbucks and CVS turns green every 6 minutes.  The traffic signal near R. J. Julia's turns green every 4 minutes.  If both turned green at 12:15 PM, when are the next three times that both will turn green at the same time?

Have a great night!

Unit Rate

We began working with Unit Rates in math class today.

The short version...

If I buy a six pack of soda for $1.80, the rate is 6 sodas for $1.80, but the unit rate is $0.30 per soda.

From hotmath.com

After briefly talking about various ways that we could solve for and determine unit rate, we each began working with a Stop and Shop circular to find food and other items that were being sold by the pound or at a group rate (3 for $9.99).  We will continue our activity on Monday as we plan a meal for our families using unit rates and purchasing items in multiple values.

Have a great weekend and remember that we have our quiz on Wednesday!
