Week of November 30 - Dec. 4, 2015

MIGHTY FALCONS,

THE CHRISTMAS BREAK IS QUICKLY APPROACHING AND THIS IS THE TIME WE ALL LOVE BUT WE MUST MAKE SURE WE STAY ON TASK SO THAT WE DON'T STAY BEHIND.  WE HAVE BEGUN WORKING WITH RATIOS AND I REALLY HOPE YOU ENJOYED THE KOOL-AID RATIO LAB PROJECT IN CLASS. I SAW MANY OF YOU MAKING MATH CONNECTIONS TO THE REAL WORLD! :)

 THIS WEEK WE WILL BEGIN WORKING WITH RATES AND UNIT RATES IN WHICH I WILL PROVIDE MORE EXAMPLES BELOW.  CONTINUE GOING OVER YOUR INTERACTIVE NOTEBOOKS ON A DAILY BASIS AND I GUARANTEE YOU WILL SEE PROGRESS ON QUIZZES AND TESTS.

RATES AND RATIOS

The ratio is the relationship of two numbers. For example you have 2 flashlights and 5 batteries. To compare the ratio between the flashlights and the batteries we divide the set of flashlights with the set of batteries.

The ratio is 2 to 5 or 2:5 or 2/5. All these describe the ratio in different forms of fractions. The ratio can consequently be expressed as fractions or as a decimal. 2:5 in decimals is 0.4.

A rate is a little bit different than the ratio, it is a special ratio. It is a comparison of measurements that have different units, like cents and grams. A unit rate is a rate with a denominator of 1.

Example:

Sarah is buying jellybeans for her best friend's birthday party. She buys a bag of 10 lb of jellybeans that costs $45. Sarah is wondering how much 1 lb of jellybeans cost.

Geometric Construction:

We will continue working on our Geodesic Domes using straws and pipe cleaners and can't wait to see your projects!

THE FOLLOWING PICTURES SHOW OUR AWESOME STUDENTS WORKING ON THEIR KOOL-AID RATIO LAB PROJECT!

Week of November 16-20, 2015

Falcons,

This is the last school week before Thanksgiving break so let's stay focused and on task. We will begin working with ratios and rates. The good news is that rates may help some of you make a better buy during the sales going on through Thanksgiving Break, now this is when you know math pays off!

Ratios

A ratio compares values.

A ratio says how much of one thing there is compared to another thing.

There are 3 blue squares to 1 yellow square

Ratios can be shown in different ways:

Using the ":" to separate the values:		3 : 1
Instead of the ":" we can use the word "to":		3 to 1
Or write it like a fraction:		3 1

A ratio can be scaled up:

Here the ratio is also 3 blue squares to 1 yellow square,
even though there are more squares.

Using Ratios

The trick with ratios is to always multiply or divide the numbers by the same value.

Example:

4 : 5 is the same as 4×2 : 5×2 = 8 : 10

Recipes

Example: A Recipe for pancakes uses 3 cups of flour and 2 cups of milk.

So the ratio of flour to milk is 3 : 2

To make pancakes for a LOT of people we might need 4 times the quantity, so we multiply the numbers by 4:

3×4 : 2×4 = 12 : 8

In other words, 12 cups of flour and 8 cups of milk.

The ratio is still the same, so the pancakes should be just as yummy.

WEEK OF NOVEMBER 9-13, 2015

STUDENTS,

WELCOME TO THE 3RD SIX WEEKS!!!

WE WILL BEGIN WORKING WITH MULTIPLYING AND DIVIDING INTEGERS AND THEN PROCEED TO AN INTRODUCTION OF RATIOS AND RATES. TIME IS FLYING BY SO WE NEED TO MAKE SURE TO STAY ON TASK NO MATTER WHAT. THANKSGIVING BREAK IS AROUND THE CORNER SO WE HAVE TO MAKE SURE GRADES ARE IN GOOD STANDING  IN ORDER TO NOT STAY BEHIND!   HELP WILL STILL BE AVAILABLE DURING LUNCH SO DON'T HESITATE TO COME IN.

GEOMETRIC CONSTRUCTION:

STUDENTS WILL LEARN ABOUT THE SCIENCE OF TOWER BUILDING AND WORK ON PAPER TOWERS TO FORM STRUCTURE AND BASES. STUDENTS WILL ALSO PLAY TOWER GAMES TO SEE WHAT POINTS ARE EASIER TO WITHDRAW FROM TOWERS.


REMINDERS:

BUS SAFETY PRESENTATION MONDAY @ 9:00AM

MAKE IT A FRESH GOOD START MONDAY MORNING!

ASK FOR HELP WHEN IN DOUBT.

TRY YOUR BEST NOT TO BE ABSENT!
