### Multiplication Facts and Division Rules

__Associative Property__

changing the way the factors are grouped does not change the product

2 x (8 x 9) = (2 x 8) x 9

__Commutative Property__

changing the order of the factors does not change the product

2 x 8 = 8 x 2

__Identity Property__

1 x a number = the smae number

1 x 55 = 55

__Zero Property__

0 x any number = 0

55 x 0 = 0

__Division Rules__

1. Any number divided by 1 = that number

55 divided by 1 = 55

2. Any number divided by itself = 1

55 divided by 55 = 1

3. Zero divided by any number is 0

0 divided by 55 = 0

4. You cannot divide a number by 0

### Parts of Electric Circuit

http://www.youtube.com/watch?v=2dqRN0Z7-_o&feature=related

1. Energy source - battery

2. CoWnductor - allows electricity to flow easily

3. Resistor - slows down the electric current

4. Insulator - stops the electric current

5. Switch - closes or opens the loop

### Facts of the Week

Each week we have 4 facts to practice.

Practice them everyday

...while eating breakfast, lunch and dinner

...in the car

...before video games

...in a tree

...on the way to soccer practice

you get the idea!

Say the facts + the answer 5 - 10 times each.

this week's facts are:

4 x 9 = 36

8 x 7 = 56

6 x 7 = 42

9 x 8 = 72

### Planning our Writing - Power Outlines

4th grade is a big year for writing

We use graphic organizers for all of our pre-writing steps.

These graphic organizers help us to organize our thoughts so we are ready to write. We start out with the basics, a power outline, which is a twist on the traditional outlining process. Below is an explanation and an example of how it is used.

**Power Outlines (from Step-Up to Writing)**

Organize your ideas for writing

T = **Topic** (What is the main idea)

RDF (**Reasons, Details or Facts** about your topic)

E – **explain** more

E- **explain** more

RDF (Another **Reason, Detail or Fact**)

E- **explain** more

E-**explain** more

RDF (Another **Reason, Detail or Fact**)

E- e**xplain** more

E- **explain** more

CS – **Concluding** sentence (restate the topic)

**Example**

T = McDonald’s

D – Milkshakes

E – creamy

E – chocolatey

D- Cheeseburger

E- juicy

E- mouth-watering good

D- French Fries

E-soft in the middle

E –crispy on the outside

E-salty goodness

### An Exciting Year Ahead

**Promethian Boards**, which I am diligently trying to master so we have much more interactive learning going on in class.

**IPod touches**. Each teacher will eventually have a class set. I am looking forward to finding many new and interesting ways to use them to improve student learning!!

**Monday, August 16t**h for all the schools in the district.

**ack to School Night**is that evening at 5:15 or 6:00.

*Homework*!

### Mission Projects Due

The rough draft of your report is due to me by Friday, May 14th.

The finished project is due on Monday, May 24th.

Mission Night will be May 25th at 5:30 in the Mark Twain Cafeteria.

### Moodle

Hopefully if we can learn it well, next year we will be able to use a lot less paper and will be doing more on computers. It is already being used by students, teachers and parents at John Muir and Corcoran High Schoool. We will be able to post study guides, class work, home work, as well as blog and chat with each other.

### CST is almost done

using the test-taking strategies and trying very hard to do their best.

### WE REALLY ARE BLOGGING NOW!

### Collecting Data

**median**- the middle number in a set of data when the data is put in order from least to greatest

**mode**- the number in a set of data that occurs most often

**mean**- the average number (add all the number and divide by the number of numbers)

**outlier**- a number in a set of data that is distant from the other numbers (an outlier may give you unreliable information)

### G2 kids are blogging

I am excited about this new tool because it allows me to give opportunity for the students to blog without them having to have an insecure email adress, without me having to give them access to my email address and it allows me the ability to oversee all posts before they are published.

### Comparing Fractions

We use the signs < (less than) >(greater than) =(equal to)

We have a nice easy trick to doing this.

1/4 is less than, greater than or equal to 2/3

1/4 is < > = 2/3

1/4 2/3 to find out, multiply the denominator of one fraction by the numerator of the other fraction. Do this to both fractions. Put the answer at the top of each fraction.

1/4 and 2/3

multiply 1x3 = 3 put that above 1/4

multiply 4 x 2 = 8 put that above 2/3

now compare 3 and 3

3 is less than 8

SO

1/4 < 2/3

1/4 is less than 2/3

### Equivalent Fractions

**1/2***Equivalent fractions for one-half are easy, because the numerator is half of the denominator.*

*1/2 - 1 is half of 2*

*2/4 - 2 is half of 4*

*4/8 - 4 is half of 8*

*10/20 - 10 is half of 20*

*SO*

*1/2 = 2/4 = 4/8 = 10/20*

Here is a song we learned to help us find equivalents of other fractions.

(to the tune of "Are You Sleeping?)

Equivalent Fractions

Equivalent Fractions

Multiply

Or Divide

Equal to One

Equal to One

To find an equivalent fraction, you need to multiply by a fraction equal to one.

Fractions equal to one are 2/2 3/3 4/4 5/5 6/6 ...etc.

So to find an equivalent fraction for 2/3, multiply 2/3 by 2/2. That would be 2x2 and 3 x2, which would be 4/6.

2/3 = 4/6

2/3 is equal to 4/6

Simplest Form

when finding simplest form, you are finding an equivalent fraction that has a numerator and denominator that cannot be reduced anymore.

To find simplest form you divide by a fraction equal to one.

The tricky part is finding a common factor of both the numerator and the denominator.

Put 15/20 in simplest form.

15 and 20 have a common factor of 5.

So divide 15/20 by 5/5. 15 divided by 5 is 3 and 20 divided by 5 is 4.

15/20 = 3/4

15/20 is equal to 3/4

3/4 is in simplest form because 3 is a prime number and because 3 and 4 have no common factors and cannot be divided further.

### Finding a fraction of a number

Alfredo has to read 24 pages in his science book by Friday. If he has completed 3/4 of the assignment, how many pages has he read?

We need to find 3/4 of 24. There are two ways to do that.

__3/4 x 24/1__1. multiply 3/x 24 = 72 and 4 x 1 =4

2. that gives us 72/4 which is a division problem

3. 72 divided by 4 = 18

4. So 3/4 of 24 is 18.

5. So Alfredo has read 18 pages.

or

__1. 24 divided by 4 = 6__

**3/4 of 24**

2. 6 = 1/4 of 24

3. 1/4 + 1/4 + 1/4 = 3/4

4. 6 + 6 + 6 = 18

5. 3/4 of 24 is 18

6. So Alfredo has read 18 pages.

### Formulas are Fun!

**perimeter**= the distance around around a figure

a

**square**has four congruent(equal) sides SO the perimeter can be found with this formula

P = 4s (perimeter = 4 times the measure of one side)

a

**rectangle**has two pair of congruent sides SO the perimeter can be found with this formula

P= 2l + 2W ( perimeter = 2 times the length + 2 times the width)

**Area**is the measure of the space inside of a figure.

the area of a square or a rectangle can be found with this formula

A = l x w ( area = length times width)
