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.

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.

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!
