SUBTRACTION – COUNTING ON TO TAKE AWAY?

This morning you will be learning another strategy to do subtraction.  We will be counting on to take away by finding the DIFFERENCE between the two numbers using the empty number line.

  •  We will be playing a game called CONVICT COUNT ON to explain how this strategy works in a fun way.
  • You can have a go on your own later or at home to use the strategy online with this SUBTRACTION ON A NUMBER LINE activity.  You can change how big the numbers are that you have to subtract and you can actually see the jumps.

You can also watch a couple of videos I made of this lesson, using an Empty Numberline to count on and count back to subtract.  You can find it on Dolphinkids by following these instructions:

This makes subtraction SO EASY!  🙂

Let me know how you go.

AUSTRALIAN MONEY

We have been looking at Australian coins and discovering which animals are on which coins.  These websites give you a lot more information.  Explore and afterwards I would like each person to explain one interesting thing they found out.  Some of you might be able to create an I-book on Australian money for this inquiry using Book Creator on the ipads.  🙂

1.  AUSTRALIAN MINT – is where all Australian money is made.  Read about our money and see what is on each side of the coin.

2. KIDCYBER – is an easier place to read about what is on our coins.

3. AUSTRALIAN NOTES – is where you can learn about famous Australians who are on our money (bank notes).

Escher Lizard Tesselation and Christmas

Here are some photos of Escher’s Lizard tesselation, which you are going to put together today.

Notice how the colours change what you see in the finished product?

And later this week we will be using what we have learnt about tesselations to make some Christmas tesselations.  Have a look at these photos for inspiration.

Isn’t Maths just so cool?  Look at how much Maths is used in Art, and Engineering, and just about everything in life….!

Flipped Learning at Work!

IMG_6644 (Small)Students have been learning Maths by watching a video of the lesson before doing the worksheets with the teacher’s help.  IMG_6645 (Small)By flipping our learning like this, students get the time to rewind the video and practise and really understand the strategy before they meet with the teacher in a small group to use the strategy.

IMG_6646 (Small)This also allows the teacher to work more with each student and give helpful tips and support.

BATTLESHIPS ON A GRID

We have been learning about grid references [A1, B3, E5]. We have been looking at grids and working out their co-ordinates.  First we will look at Maths Dictionary for Kids – C for co-ordinates to see which letter or number comes first.  [Challenge question: which is the X and which is the Y axis?]

Then we will be learning how to play battleships with our partners.  When you have played a game with a partner, you can have a go at playing the on-line game below.

BATTLESHIPS – a game to check your grid references.    You need to call out the grid reference before you bomb it.  🙂

COACH CASH SHOWS US HOW TO CASH UP!

Room 6 had a visit from Coach Cash earlier this term to tell us how to manage our money.  Two our of students were journalists for the day: Izzy and Kayne and this is what they wrote about her visit.   [Well done to both of you.   🙂  Mrs Veary]

IMG_5701 (Small)    Coach Cash Came to our school
I am a  Journalist for Coach cash .  I am doing  Key Cards.  Coach cash chose Kayne and Ruby for a Key Card Show to show  the class.  She showed that us she was going to the cinemas.   She showed us how the machine works  through the cinema’s bank account and the Commonwealth Bank. She said there was a special quadpack for 45 dollars and she had 50 dollars to spend, but the tickets were only 15 dollars . So she said to just buy the tickets and get snacks from home.

Part2  The soccer season is in 2 weeks’ time.  You have to buy soccer boots.  There are different offers.  There is an offer for 50 dollars but is gives free jellybeans  and you get them now or another one for 40  dollars and you get 10  dollars change, but you get them in 2 weeks time or you get  the ones for 45 dollars and get  5 dollars change and you get them right now.  We had to choose. She bought the 50 dollars one and then she goes home and her mum says, “Oh good, but where are your shin guards?”

Introduction
Coach Cash (Amber) is a person that works at the bank. She taught us two courses.   The first one was money, money, money, and money.
The second one was get the cash, put it away and save some too..So those were the courses.

Using A Key Card
Coach Cash taught us how to use a Key card. Coach Cash used Ruby and Kayne as assistants. This is how it worked, there were two money boxes with string attached to the money boxes and Ruby and Kayne were talking to each other. Ruby was the bank and Kayne was the person who was using the key card.  Kayne had 50 dollars in the bank. He wanted to get a family pack and the family pack came with a hat, popcorn, ice cream and a bottle of water.
Kayne had no more money left to buy tickets.
So that is a lesson on spending money wisely and thinking of more important stuff like buying a house or a car.

It’s so lovely to have journalists telling you about special events in our room.  Thank you both, Kayne and Izzy.  🙂  Mrs Veary

 

What causes the seasons on Earth?

How do the seasons change across the world?

What causes them to change?

How can we explain these changes and why they are not random?

Watch this video clip to try to explain this in your own words.

We will be talking about the seasons during Maths on Wednesday when we do “The Trip Around the Sun”, working out facts using calendars and the seasons. Have a go at watching this tonight at home and we can talk about it tomorrow at school.
[This is called ‘flipped learning’ where you guys get to do the watching in your own time and then we do the talking and interesting learning about it in class time.]

Chances of ….?

In Maths we can work out how likely it will be that an event will occur.   It could be certain, likely or unlikely.

When it comes to a dice or a spinner, you can work out how likely by saying 

You have a 1 in 6 chance of winning; or you have a 1:6 chance….. depending on the number of possibilities given.

We will explore how this works by using the spinner in this SPINNER manipulative.

BOX DRAW manipulative – how many times will you draw out a certain colour depends on how many of each are in the box.

COIN TOSS manipulative – it’s interesting to see how many times heads or tails comes up when you toss a coin.

Good luck and have fun taking your chances on these activities! 8:)
