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.

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 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.]

BATTLESHIPS ON A GRID

We are learning about grid references [A1, B3, E5]. We will be 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.  🙂

ROTATING MATHS GROUPS – Game #2 TIMES TABLES

Please note that you may need to enable Flash Player for some of these games.  Find a logon that works or skip those games it it won’t work for you, and go on to the next post or game.

Today in Rotating Maths Groups we will continue learning about multiplication.  This is number 2. of times tables activities. Computer will be practising their multiplication skills doing these activities:

1.   FLYING HIGH

2.  CONE CRAZY

3.  GRAND PRIX (a bit of a challenge for your times tables)

Work hard and have fun learning how to multiply!

Adding Two-digit Numbers

In Rotating Maths Groups today, with Teacher you will be working on NA10 – written strategies for addition.

When you need to add two digit numbers, sometimes you have to regroup to bridge ten.   This activity shows you how, using MABs.

ADDITION DEMONSTRATION

Now you should be able to use this  (and remember our Cheat Sheet) or Tens Frames to solve any addition problems.   😆

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).
