Amazing Alegbra!!!

Posted on

Hello,

Today we had independent maths, I did algebra. I know we have to wait till the end of the year to do algebra, but I WANTED TO BE CHALLENGED!!! It’s actually kind of easy once you get the hang of it. I first read Miss C’s maths dictionary to get the basic information, I then did two tests on maths online, on the first one I got 100% and on the second one I got 80%. I think it is good that I am learning algebra because I will get better understanding when we do it at the end of the year.

What do you think of algebra?

Terrific 3 Way Conferences

Posted on

Hey Bloggers,

Yesterday we did 3 way conferences. You’re probably wondering what they are… They are just like Parent & Teacher interviews except the teacher isn’t talking to mum or dad till the end. We have to host it. You need to tell your parents something about each subject, ( Reading, Writing, Maths and Inquiry.) We had to write a script so we don’t say stuff like umm…. Uuuuuuhhhh… Here is my script:

 

Here is is a reflection of last night when I did it:

If I could fix anything about last night I would fix how quickly I talked as mum and dad said I talked as if I was being chased!

How did you feel?


Alarming Arrays

Posted on


Guess what we did boring maths all week…..
Just Joking
We have started an awesome unit on alarming arrays and I’m here to tell you all about them.
So say your number was 40.
Patterns: a pattern is a way to make a number here are patterns that make 40Columns: Columns go up and down eg. 5 columns of 8 =40
Rows: Rows go sideways eg. 8 rows of 5 =40
Addition: this repeative addition it’s not normal addition you add the same number multiple times to get one number eg.10+10+10+10=40
Multiplication: This is another way to work them out eg. 2 down 20 across =2×20=40
Factors: 1,2,4,5,8,10,20,40
Multiples:40,80,120,160,200,240,280,320,36,400,440,480 a multiple of a is in the Multiplication table of the number eg.
Square Numbers: 40 isn’t but 36 is, a square number is a number times by itself eg.6×6=36
Primes:40 isn’t a prime number but 41 is this means 41 is a natural number greater than 1 that has no positive divisors other than 1 and itself.
Composites: 40 is a composite number which is a positive integer that has at least one positive divisor other than one or the number itself.

What is your favourite number, is it a prime or a composite and is it square???



Rad Renaming

Over the past two weeks we have learnt what renaming is, at first I was like OMG what is renaming??? Do you know what it is? But luckily my fabulous teacher Miss C told and taught us what it is.

In the end we made a video I was with my friend Jasmine, it took us 2 hours to make. How I’m an expert!

The Process & stuff

Over the past few weeks we have done the Maths Toy Investigation! I made a toy called Polly Parrot, the troubles I had were the net, the construction and the isometric drawing.  Here is the maths in her construction:


Fruit Fractions

In class we are learning about fractions and because Miss John is nice she let us use fruit to help us. Over the last two days we did this. First we used oranges to help us with quarters, Miss John asked us some questions like if I had 50 oranges then put them into thirds how many thirds would I have? The answer is 150.The next day we used mandarins, our mandarins were divided into eight segments.  Today we are doing watermelon and dividing it into 20ths . We cut the watermelon in half then in quarters then into 20ths. The circumference was 70cm and my piece is 3.5cm and weighs 311 grams.

Dot graph

On Friday the 16th of May 2014 we had kitchen garden. We ate spanakopita and it was GROSS! After lunch we went into 4A and we did a dot to rate it. The queue was so big I could fall asleep! Anyway about the rating we had to rate it from 0 to 10. When  I added it up mine equaled to 3.
4A report: 4A really loved it! I absolutely could not believe it, it was amazing, incredible I could not believe it!
4B report: 4B had very different scores! From high and low I had no idea 4B had the most variety!
4C report: 4C had most of their dots in the middle! It was umm……. I don’t really have a answer!
