Is it inherited/Instinct or Learned/Acquired?

Inherited Traits are traits that are passed down to offspring from parents.

Examples: hair color, eye color, size and shape of facial features, etc.

Instincts in Organisms are behaviors that do not require learning and are done in order to survive.

Examples: baby chicks pecking out of their shells, babies crying when they are hungry, etc.

Instinct in animals is something which is engrained into that animal when it is still developing and hasn't even been born yet. Instinct is thought to be hereditary, passed on from the parents so baby animals instinctively know how to get food from their parents. Although instinctive behaviour is behaviour at a very basic level, without natural instinct many animals simply would not survive as baby birds wouldn't know how to get food from their mother and beavers wouldn't know how to build a dam. Many animals rely on their instincts to sense approaching danger, or when searching for a mate.

Learned behaviors are behaviors that are learned throughout an organisms lifetime.

Examples: riding a bike, walking, sports, gymnastics, animals hunting skills, squirrels cracking nuts

Acquired Traits are traits that are acquired throughout an organisms lifetime.

Examples: length of hair, weight, height, sloths fur appears green over time due to algae growing in it

Prime and Composite Numbers

Prime Numbers are numbers with ONLY 2 factors.
Those factors are 1 and itself.









Composite Numbers are numbers that have more than 2 factors.


Here is the Sieve we did in class today (and should be in their Math notebooks). Using the numbers 1-100, we crossed out all the multiples of 2, 3, 5, and 7. The remaining numbers that were not crossed out, are PRIME.

These charts are a fabulous reference for determining prime & composite numbers. These are also glued in students math notebooks.

REMEMBER:

• The number 1 is neither prime nor composite because it's only factor is 1.

• The number 2 is the ONLY EVEN PRIME number.

• Just because a number is ODD, DOES NOT mean it is prime!!
• Examples are 9, 15, 25

Check out this video to help you remember what the prime numbers are from 1-100!

Factors and Multiples

 

 

FACTOR FRENZY!!

Factors are numbers that are multiplied to get a product.

Jared has 12 flowers. He wants to plant them in his garden in equal rows. How many different arrangements of equal rows can Jared plant his flowers?

Step 1: Find all the multiplication equations that have a product of 12.

1 x 12
12 x 1
2 x 6
6 x 2
3 x 4
4 x 3

Step 2: List each factor ONLY ONCE.

Step 3: The factors of 12 are: 1, 2, 3, 4, 6, and 12

MULTIPLES MANIA!!

 

 

 

Multiples are the product of a whole number and any other number.

 

 

The multiples of 2 are: 2,4,6,8,10,12...... (skip counting)

 All multiples of 2 are EVEN numbers.

 

 

The multiples of 5 are: 5,10,15,20,25,30....(skip counting)

 

All multiples of 5 have either a 5 or 0 in the ONES place.

 

If you multiply 5 x an EVEN # the product will have a 0 in the ones place.

If you multiply 5 x an ODD # the product will have a 5 in the ones place.

 

 

 

 

Check out this link for fun songs for all the multiples! We've listened to several in class already! :)

Properties of Multiplication

Commutative Property:

two numbers can be multiplied in any order and the product is the same




Identity Property of Multiplication:

the product of any number and 1 is that number



Zero Property of Multiplication:

the product of any number and zero is zero

Who likes Cappucinno?

Kristina brought her bunny, Cappucinno, to visit our classroom today. It was very exciting to have a real life example of an animal in the vertebrate mammal group! It was fun to have her with us all day! We all enjoyed getting to interact with her. Check out our pics...

Classifying Organisms

                                   Living Organisms

Animals are classified into 2 groups:

Invertbrates- animals with no backbone
Some with hard shells (snails, scorpions)
Some with soft bodies (jellyfish, worms)

Vertebrates- animals with a backbone
Mammals & Birds (warm blooded; constant body temperature)
Reptiles, Amphibians, & Fish (cold blooded; body temperature changes with the environment)

Plants are divided into 2 groups
Flowering Plants- produce seeds within flowers or fruits that contain seeds

Non-Flowering Plant-plants that produce seeds within cones or produce spores instead of seeds (ferns, moss)

 Moss

  Spores are found on the underside of the leaves

  Ferns

   

National Walk @ School Day, October 10, 2014

At CFG on Friday, students were able to participate in National Walk @ School Day. Students wore thier CFG shirts and were able to walk during recess, on a track that Mrs. Long set up. Parents were invited to come and walk with students. It was a beautiful day for walking at CFG!
