What do you use money to buy?

In this clip we look at Australian money. See the different coins and notes that make up our money system.

We investigate if size, (in coins) does matter. Check out how many 5 cent pieces you need to make two dollars. We also look at some currencies used around the world. Find out which country has the yen.


Things to think about

  1. 1.Which is worth more, a two dollar coin or 27 five cent pieces? How many rows of 8 five cent pieces would you need to equal two dollars? Which is worth more, 3 one dollar coins or 9 fifty cent pieces? How much would I have altogether if I had, 2 one dollar coins, a two dollar coin, a fifty cent piece, 2 twenty cent pieces and a ten cent piece? Would you have enough to buy a piggy bank worth five dollars?
  2. 2.What did people do before money was invented? List all the bank notes in the Australian money system. Which note has the highest value? By size, what is the biggest Australian coin? However which Australian coin has the highest value (worth most)? How many 50 cent pieces make one dollar? What is the currency of Japan and India?
  3. 3.Put the Australian coins in size order. Now draw them in order of value, largest to smallest. What do you notice? How many fifty cent do you need to make up the amount of $1.50 (one dollar and fifty cents)? Imagine if you had only 10 cent pieces. How many would you need to make $1.50? How many 10 cent pieces make fifty cents?
  4. 4.The school canteen has a roll or fried rice for two dollars. A drink for one dollar and fifty cents. An apple or bag of chips for 50 cents. You check your pockets. You have 3 one dollar coins, a two dollar coin and … a dirty tissue! What would you buy with that money?
