I swam in this stuff once before!

From the Daily What:  Lights Out: Surfers generate beautiful bioluminescent waves off the coast of San Diego by disturbing a bloom of warmwater phytoplankton Lingulodinium polyedrum, causing a chemical reaction which produces a flash of blue light.

Though red tide can be harmful in certain circumstances, this particular algal bloom has a low-level toxicity that is safe to swim in.

It wasn't this wild when I did it, but it was pretty darn cool!

GCF

Greatest Common Factor.  Today we learned about determining the GCF by listing factors and using prime factorization.  Here are some of the notes from class today.

There is more than one way to get the prime factorization of a number, but the answer will always be the same.

Here's the solution of the first problem on tonight's homework:

By finding the prime factorizations of each number, we can compare what they have in common and use those common values to determine the GCF.  In this case, each value has two 3's in it's prime factorization so 9 (3X3) is the greatest common factor.

Let's watch Bob's video from class today:  Bob!

Another video on GCF:  (This guy has even better upside down writing skills than me!)

I hope that this helps!

Tonight's homework is to complete the GCF worksheet.  There are six problems on the paper and we already did #1 in class (see picture above).  You will be able to skip EITHER #4 or #6 if you would like.  If you would prefer to do all problems (that's awesome) you can do both #4 and #6 in addition to the regular ones.  If you do all six problems and get one wrong, it can still go in the 100's box!  There must be 5 correct problems on your paper to go into the 100 box!

Good luck with the homework!  Have a good night!

It was really nice to see all of you today!  I missed you on Friday!

Converting between fractions and decimals

Hey everyone!  As you know, I will not be in school on Friday for Rosh Hashanah so I hope that class goes well and you do your best work with the sub.  You will correct the homework from today and work on a class assignment during the period.  If you finish early, there should be a challenge problem for you!

In class today, we began looking at converting decimals to fractions and fractions to decimals.  I was going to type out a big long informational post, but I found two great pages on mathisfun.com that covers everything.  If you have questions, click the links below.


Converting decimals to fractions


Converting fractions to decimals

These links should be a big help!  Fractions should always be in lowest terms when possible.  Remember that when you divide a fraction to turn it into a decimal, the NUMERATOR goes inside the house and the DENOMINATOR is on the outside.  Be on the lookout for repeating decimals and use bar notation when you find one.  Otherwise it should be Terminating.

Have a lovely weekend.  I won't be posting tomorrow or Friday.  L'Shana Tovah if you are celebrating the Holiday.  :)

Can you figure out why this won't work?

He he he, ouch!

LCM

Today we began working on LCM...

Here are some reminder slides from today's lesson:

Try the game from class!

Tonight's homework is the LCM worksheet.  Remember that you don't have to do the notes side and to read the directions along the side of the paper.  You MUST do #1-8 and 53 and 54.  Choose at least 10 problems on numbers 9-52.

Have a great night!

Comparing and ordering fractions

Today we began working with comparing and ordering fractions.  When we compare or order fractions, we can take three approaches.

The first is using logic.  Sometimes you can use common sense to figure things out.  For example if one number is bigger than a half and the other is larger than a half, you don't really have to any calculations.

The second method is probably my favorite.  If we cross multiply going "up on a diagonal" we can easily compare fractions.

Finally the last method is finding common denominators and then comparing the fractions.

Since finding common denominators can be tricky, check out this video to help you...

Another one:

And one more:

Though all of these videos show using Least Common Denominators (LCD) in addition and subtraction problems, the process is the same.

Tonight's homework is to complete the comparing and ordering fractions worksheet.  Remember that you only do the side with the practice problems, #'s 1-22.  

Good luck!  More review on this tomorrow!

Quiz today!

Nothing to report on the quiz just yet!  If you were absent today, make sure that you stop by on Monday to arrange a time to make up the quiz!

I hope to have the quizzes corrected by Tuesday so that you can see your score!  :)

Enjoy the weekend!

First Quiz Tomorrow.

Hey everyone!  As you know, we have the first quiz of the year tomorrow!  I want to make sure that you are as successful as you can be, so be sure to study this evening!!!

If you want to do a bit more practice, you can work on the problems we did in class.  They are all below in this post.

Practice prime and composite sorting...
Pick your own numbers.  You can check out my old prime and composite post here!

 Practice your divisibility rules...
Pick your own numbers and use the rules from this post to help you remember!

Practice working with fraction models...

Circle 1/5 of these soccer balls.  Or 3/8, or 1/20.

 Try 5/8 of these cowboy boots, or 1/4, or 5/6.

 Circle 1/3 of the ice cream cones, or 2/7.

Practice Probability...

Make up your own probability problems using the items from my junk drawer.  Combine them to make it more challenging.  Be sure to simplify!

 Practice working with ratio...

Use these items to make up ratio problems.  Again, be sure to simplify your answers.

You have your study guide as well as your old homework papers to practice for the quiz tomorrow.  Come in well rested and prepared to show your best work!

-Miss K  :)

Probability

We were able to play with probability in class today!  Here are some highlights...

We can examine Probability in similar situations...

We can use probability to examine almost anything...

Or use traditional means of looking at probability...

Tonight's homework is to complete the probability worksheet.  The study guide is also due tomorrow.

Have a good night!

Perfecting percent!

I am 100% sure that I had fun in class today and I hope that you found at least 80% of class enjoyable.

We started looking at percents today.  I love percents because they often mean that I get to go shopping!!!

(I love shopping!)

Or we get to eat!!!

We also use percents for grades, surveys and discussing time!

Tonight's homework is to complete the percent worksheet.  Please remember that #7 is optional!!!!  Also, the study guide is due Thursday.

Remember that percent is per 100!

If you want to challenge yourself and practice working with percents, fractions and a few decimals, check out this game!

Fraction Models

Today we began reviewing fraction models.  Be sure to complete your homework, fraction models worksheet, tonight.  It should be pretty straight forward!
