Recently, when Miss Jordan was doing her grocery shopping at the local supermarket, she investigated the cost of a variety of typical Australian foods. Supermarket prices often change, as each new week brings about a new catalogue with different sales and savings. The presentation below shows the prices she collected last weekend.

Were you surprised by any of the prices of these grocery items?

Do you eat any of these foods?

In Maths, we have been learning about rounding. Rounding numbers means to change numbers to make them easier and more convenient to work with. We round numbers when we use money all the time.

As you may remember from our currency post, Australia’s smallest value of money is the five cent coin. We often need to round prices up or down to the nearest 5c when we’re out shopping. The table below shows some examples.
