How does the Census help us?
Today in class we had a look at the website Spotlight, which is created by the Australian Bureau of Statistics to inform people about information collected in the Census and how it is important.
It provided us with information about the population of our area, the number of Australians with the same age as us and our ancestry. At the end, it produced a neat infographic like the one below which each of us printed.
You might like to log on to the website at home and how you compare to the rest of Australia. If you find an interesting fact, we would love for you to share it with us!
Homework – Weeks 3 and 4, Term 3
Wow, week three already!
Here is our homework for Weeks 3 and 4 of Term 3. All of our tasks relate to the learning we have been doing, or will be doing, in class, especially our work on average, operations and measurement in Maths, grammar and vocab in English and our class novel for integrated.
This homework is due back on Friday, 12 August. Our organisation tip is to ensure you’re in the right frame of mind before
beginning homework. No point if you are really tired or exhausted. Have a snack, something to drink or a ten minute break if needed before starting.
When you finish your homework, why not score yourself on our marking rubric – it should be the same score I give you!
Some websites that might help you to complete tasks this week include:
- Wimp Yourself: http://www.wimpyourself.com
- Census 2011: http://www.census.gov.au
- Bureau of Meteorology / Victoria: http://www.bom.gov.au/vic/index.shtml
Area and Perimeter
Today in class we spent time learning and clarifying the meanings of the two terms area and perimeter.
Area is the amount of space on the surface of a shape, or inside a two dimensional shape.
Perimeter is the distance around the outside of a shape.
Here a a song that might help you to remember the difference between the two!
This activity below will help you remember the difference between the two terms and show you how to calculate the area and perimeter of different shapes.
Fractions, Decimals and Percentages
On Friday, we continued our work on fractions, decimals and percentages. We started looking at how we could find the percentage of something when we had an amount that was more than or less than 100. To help us, we took to the school car park.
We found a row of 20 cars, and from this row were were able to work out some fraction, decimal and percentage amounts of the colours of the cars. Here is some of our work. We recorded it on the footpath so everyone could see.
To help you further practise matching fraction, decimal and percentage pairs, why not try out this game from the BBC’s fractions, decimals and percentages collection (there are more games and instructions if you follow the link!)
Maths Map: Learning Maths with Google Maps
Fly down Gwendoline Drive and count the number of bins out for collection. What percentage are recycling bins?
These are the sorts of questions we were answering in Maths this morning. No, we didn’t all suddenly get our pilot’s license! We were using Google Maps to help consolidate our understanding of fractions, decimals, percentages and worded maths problems.
This morning we had a look at a Maths Map, which is a Google Map containing a large range of maths questions. Not only did we have to work out what the question was asking us to do, but we had to use the maps to find the answer to the problem. Some of them required us to look at street maps, others satellite maps and some even fly around in Street View. Here’s an example:
All of our maths questions were on streets around our school. It really helped us to put maths into context and use it to solve real problems. Rather than just colouring in fractions on a worksheet or doing a page of sums, we had to find the information to solve the problem. We also got to have fun doing it in a creative way. Some of the reflections students made on the activity include:
There were different levels of questions to choose from, so students were able to challenge themselves with more difficult tasks. Some reflected that they didn’t feel there was enough challenges, so we shall look at extending this part of the maths map. Everyone was really excited by the task though and enjoyed it, and we can’t wait to have another go! It is amazing that the students were able to use the maths knowledge and content they learn in class and apply it to actual problems, and help see how it is useful to them.
Make sure you check out our maths map (it’s under the Games menu at the top of the blog). Some of the students extended themselves by creating their own questions which we are adding to the map. Can you think of some more questions for us to solve? Post them in a comment (without the answer) and we will add them to our map!
Fractions, Decimals and Percentages
In class at the moment we have been learning about fractional and decimal numbers and being able to convert between the two (for example, understanding that 0.42 is the same as 42/100). Today we were introduced to percentages and how they link to decimal numbers.
You may like to practise the skills you have learnt in the game below. If you are unsure of what a percentage is, you can just look at the counter on the side to see what percentage you are up to.
Footy Maths – Round 5
Today we played round five of Footy Maths. There were some changes to the ladder after today’s games; have a look below to see where your team now sits.
Points | W | D | L | F | A | % | |
The 7 Chosen Ones | 20 | 5 | 0 | 0 | 21 | 3 | 700.0 |
Random Peoplezzzzz | 12 | 2 | 2 | 1 | 19 | 10 | 190.0 |
Malik and the Recruits | 10 | 2 | 1 | 2 | 16 | 10 | 160.0 |
The Smiggle Team | 8 | 2 | 0 | 3 | 19 | 30 | 63.3 |
The Brainy Bunch | 6 | 1 | 1 | 3 | 15 | 24 | 62.5 |
Pink Ops | 4 | 0 | 2 | 3 | 8 | 21 | 38.1 |
Next weeks games are:

Learning about fractions
In class this week we have been exploring fractions, including what fractions are (equal parts of a whole or group), how to represent them and what they are equivalent to (the same as). We have been using a fraction wall to help us with this work. You may like to download this fraction wall for home to help remember how they compare.
Today as a part of our maths investigations we played the following game. It is fantastic for identifying and recognising fractions, and understanding/matching equivalent fractions. Everyone seemed to understand it really well!
To play, you can download the file I have created below and print it out at home. You will need two boards – one for each of the people playing. You will also need two 6-sided dice and a selection of counters or objects you can use to cover the squares.
Take turns to roll the two dice. Lets say you go first and roll a 2 and a 5. Using these two numbers, make a fraction (2/5) by placing the smaller number on top. As your fraction is 2/5, cover up two fifths on the gameboard. Now it is your partners turn to do the same.
The tricky bit is when the board starts to fill up. What if I roll 1/2, but I have already covered up both of the 1/2 pieces? You can start to match equivalents (cover 2 of the 1/4 rectangles, or 3 of the 1/6 rectangles). It works the same in reverse – if you roll 2/4 you can cover 1/2. You will also find you might get 4/4 but not have 4 quarters available to cover- you may need to cover the whole! You may also reach the stage where you have to skip a turn.
The winner is the first person to cover all the places on the wall.
Why not try playing this game at home and see if your child can explain it?
After playing the game we also went further to ensure we have an understanding of equivalent fractions and can compare fractions to see if they are bigger or smaller than one another. There are some games you can play online to help you practise these, including Fraction Frenzy, Tony’s Pizza Place and Melvin’s Make a Match.
