Social Studies:
On Friday, we started learning about the Peoples of the Northwest; specificially, one group of Alaskan Natives known as the Haida people.  Below, I will provide links to pages that will give you more information.
From the links titled: Potlatch,  Haida Culture 1, and Haida Culture 2, make up at least three questions for your fellow classmates.  Next week, your classmates will be given copies of the same information to read and they will be asked to answer your questions.  For those of you that complete this, you will be allowed to continue working on your totem poles!

TRIBES OF THE NORTHWEST:

November 23, 2010

Next week, students will be assigned a "Cereal Box Book Report!" (check the "Documents" link for a letter to families called: "Cereal Box Book Report."  Students will select a book to read and fill out templates that display literary elements; the templates will be glued onto the box.  They will also decorate the box in a way that describes the book.  This report will end with your student presenting a cereal/book "commercial" to the class!

• Walk to Read:  Latest story and spelling words are located in the "Documents" section!

• Math:
• Rules of divisibility
• A whole number is divisible by 2 if and only if the ones digit is even.
• A whole number is divisible by 3 if and only if the sum of its digits is divisible by 3.
• A whole number is divisible by 5 if and only if the ones digit is 5 or 0.
• A whole number is divisible by 6 if and only if it is divisible by 2 and 3.
• A whole number is divisible by 9 if and only if the sum of its digits are divisible by 9 (or 3).
• A whole number is divisible by 10 if and only if the ones digit is 0.

MATH

Factors

A whole number that divides exactly into another whole number is called a factor of that number.

So, 4 is a factor of 20 as it divides exactly into 20.

So, 5 is a factor of 20 as it divides exactly into 20.

Note:

If a number can be expressed as a product of two whole numbers, then the whole numbers are called factors of that number.

So, the factors of 20 are 1, 2, 4, 5, 10 and 20.
*************************************************

Multiples
The products of a number with the natural numbers 1, 2, 3, 4, 5, ... are called the multiples of the number.

For example:

So, the multiples of 7 are 7, 14, 21, 28, and so on.

###### Note:

The multiples of a number are obtained by multiplying the number by each of the natural numbers.

For example:

• multiples of 2 are 2, 4, 6, 8, …
• multiples of 3 are 3, 6, 9, 12, …
• multiples of 4 are 4, 8, 12, 16, …

eg. - Composite number 36
A prime number is a whole number that is greater than one and has exactly two factors, 1 and itself.

A composite number is a whole number that is greater than one and has more than two factors. The number 1 is neither prime nor composite. Number 2 is the only prime even number. The prime numbers less than 50:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47.
The Prime numbers are:
2, 2, 3, 3  OR
22, 32

Prime numbers:  22, 32

Expository Writing Project

Requirements:  Turn in a one page report based on the research you have gathered on your particular animal or creature.

In 3-5 sencentes, explain five interesting facts about your animal or creature. In 3-5 sentences,  describe this animal or creature in detail.  What does it look like? (Is it furry, or does it have scales?  Does it have feathers or does it have a shell?) In 2-5 sentences, explain how this animal or creature interacts with its environment:  Where does it live, what does it eat, what does it do? Doing the best you can, include a visual representation of your animal or creature. Orally, present your findings to the class.
