# Decimal match-up

8 - 10 years Developed in partnership with Education Services Australia

The Australian Curriculum sets the goal for what all students should learn as they progress through their school life. Skills in the Year 3-4 curriculum include:

• visualising, describing and ordering tenths and hundredths
• visualising, describing and ordering 1-place and 2-place decimals
• knowing how to read decimals
• recognising that tenths written as fractions and as 1-place decimals have the same value
• recognising that hundredths written as fractions and as 2-place decimals have the same value
• solving problems using equivalent fractions for tenths, hundredths, 1-place and 2-place decimals.

It’s easy to help your child practise these skills as part of everyday life – just use these simple ideas.

## Decipher decimals

To master decimals, your child first needs to learn how they are read differently in different situations:

• 1.52 is read as one point five two or one and 52-hundredths
• \$1.52 is read as one dollar and fifty-two cents or one dollar fifty-two
• on a digital clock, 1:52 is ready as one fifty-two (and there are only 8 minutes until 2:00, not 48 minutes).

• read and measure decimal measurements
We need to cut 1.6m of ribbon, can you help me measure it?
How much are mangoes this week?
• read the time on digital clocks
• convert decimals into fractions
Our ceiling is 2.4 metres high, what's that as a fraction? Two and four tenths of a metre, that's right!
What's 7.99 as a fraction? Seven and ninety-nine hundredths!
• convert tenths and hundredths into decimals
The suitcase weighs nine and two tenths of a kilo - that's 9.2 kilos.
This measures one and seventy-one hundredths. What's that as a decimal? (Answer: 1.71)

## Go online

For online reinforcement, Decimaster: match-up will give your child practice at:

• representing tenths as decimals, fractions and on a grid
• connecting the different ways to represent tenths.

Wishball: Hundredths will give your child practice at:

• understanding place value (tens, ones, tenths and hundredths)
• doing simple addition and subtraction with decimals.
