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!

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.

Holidays… time to relax!

After a long term two, I think everyone is now looking forward to a relaxing two weeks holidays! Make sure you take the time to rest and enjoy lots of time with your family and friends. Before you do rest though, if you haven’t already, don’t forget to book a time for a Student Led Conference next term.

If you are still looking for something to do, you may like to play the game below. See if you can figure out the aim and objective on your own. I have only linked to it, rather than embedding, because the sound is very irritating if you don’t want to play!

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!)

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.

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.

Tony’s Fraction Pizza (Fractions Game)

This fractions game, Tony’s Fraction Pizza Shop, requires a number of skills to play. First, you need to ensure you read the instructions carefully when they come up on the screen. Your aim is to make as much money for the pizza shop as you can in 5 minutes. Secondly, you will need to know some equivalent fractions. Good luck!

  • Step 1.) Read the client order. A sample client order might read “I’ll have a large pizza, 1/2 pepperoni, 2/5 mushrooms and 1/10 bacon”
  • Step 2.) Select pizza size. In this case, select “large”. This will cause the denominator to change to 10, as a large pizza has ten slices.
  • Step 3 and 4.) Select toppings. First, click on pepperoni and apply to half of the pizza (5 slices). Next, click on mushrooms and apply it to 2/5 of the pizza (4 slices). Finally, click on bacon and apply it to 1/10 of the pizza (1 slice). NOTE – if you make a mistake, select a different pizza size and then re-select the original pizza size to get a new pizza.
  • Step 5) Click on “send”. If you are correct, you will make a sale. Incorrect pizzas will cost you! Enjoy the game!.
