Converting decimals to fractions and vice versa

This week our focus is on converting decimals intofractionss and vice versa.
To begin with we have to establish what the WALT is




We also need some base knowledge:

1 whole = 1
1/2 =.5
1/4 =.25

We also need to know about decimal place value.

We are already aware that the place value columns are

the ones
the tens
the hundreds
the thousands
the tens of thousands
etc

When working on the other side of the decimal point it is almost the same, but with some subtle differences.
The column directly after the decimal point is the tenths, followed by the hundreths and thousandths etc, as shown in the graphic below.




This is a good point to pause and ensure we all understand this, and soon we will move on to converting decimals to fractions.
