Chunking With Oriana And Megan

Lately in maths, we have been revising the chunking method for addition. The chunking method involved chunking – or splitting – a number into its tens and ones to allow for easier mental computation. All the students practised this method in their books before creating a presentation on the iPads.

You can find below Oriana and Megan’s presentation:

For more presentations, head to our students’ individual blogs.



Multiplication methods

You will find below some multiplication methods that our class investigated. The children worked hard to create quality videos to explain their favourite method. Have a look at the videos, and don’t forget to answer our question at the end: which is YOUR favourite method? We’d love to hear about it!

The area model – by Zoe and Eliza

The expanded algorithm – by Jack and Wade

Mental computation – by Holly, Jennieva and Bri [The Wild Mikes]

The Lattice method – by Ben and Hamish

Let us know which is YOUR favourite multiplication method:


Wil and Harry H: we prefer the Lattice method!

Lately in maths, we have been investigating different methods for multiplication. In pairs, the students are creating quick videos using the app “educreations” to showcase and explain their favourite method.

Here is Wil’s and Harry H’s – the Lattice method:

There will soon be another post showcasing all our class’s favourite methods.


Building Maths Skills Everyday

Wondering how you can best support your child with maths? Here are some examples of everyday activities that help develop strong maths skills:

  • Play Monopoly!

The game of Monopoly has so much maths in it… Think about it: as I roll my two dice, I subitise (instantly recognise the patterns of dots and the number they represent) the numbers rolled. By adding these two numbers, I practise quick addition facts, some of them doubles. If I roll doubles… let me think, how likely is that? Hey, there’s some chance and data in this game!

The board is organised in 40 squares and 4 corners… As I navigate my way around the board and go around a corner, I chunk the number I just rolled so I can quickly work out where I am going to land.

As I buy property, pay rent, receive payments, I get to handle Monopoly money and I practise adding and subtracting, using multiples of 5, 10, 20, 50, 100 and 500! When I purchase houses, I get to use multiplication to pay the banker. Division if I want to work out how many houses I can afford…

When I land on Income Tax, I must decide whether to pay $200 to the banker, or give them 10% of my wealth… Hmmm… which way is going to cost me the least?

Monopoly is full of maths, and best of all, it’s also full of fun and family time. 🙂

  • Visit Target, Kmart or BigW when they have one of their 20% off sale!

What a great way to practise our understanding of percentages, and the parts that make up a whole!

How many ways are there of calculating 20% off? I could think of 20% as the fraction 1/5, or I could start with the whole price and only take 4/5 of that price into account to work out how much the item is going to cost me.

If the sale is 20% off, that means $20 dollars off in every $100. That’s the same as $2 off in every $10, or $1 off in every $5. Perhaps this strategy can help me best…

Ask some ‘what if?’ questions: what if the initial price had been $100, $80, $50? Is there a pattern?

  • Forget about the mess, let the kids cook!

Following a simple recipe can give plenty of tasty maths practice. Adjusting a recipe to cater for more guests will make us think of important concepts such as proportion and fractions (of cups).

  • Get the kids to help you budget for your next family purchase;
  • When planning for a trip, get the kids to read bus, train or plane timetables and work out the best itinerary.

Maths is all around us. These are just a few examples of everyday activities that involve maths and that everyone can use on a regular basis to support their child practise some very important skills… and enjoy themselves along the way!


Blog Maths

Article written by Eliza and Levina

In maths our class has been learning how to make pie graphs. The pie graph was about who has visited our class blog.  Firstly we drew up a table of all of the countries that had visited our blog, then we did the tally, fraction, decimal, percentages, then we worked out the sector sizes. Once we worked out the sector sizes we were able to draw our pie graphs, we used a protractor  to draw up the sectors.
