Mathematics involving money

Close to all our hearts in year 7 & 8 is money. Today we were learning to:

• round money amounts to the nearest $1.00
• round money amounts to the nearest $10.00
• round money amounts to the nearest $100.00

Rounding down or up amounts helped us to estimate the cost of buying a number of items at the same time.

Can you round these amounts to the nearest $1.00
$5.85  $37.15  $58.35

Can you round these amounts to the nearest $10.00
$15.75  $87.99  $28.70

Can you round these amounts to the nearest $100.00
$367.75  $87.99  $549.70

Why would having good estimation skills help us?
You know roughly how much your spending (Courtney)
You know if you're spending too much (Crystal)
So you can budget with your money (Emily)
