Notes and Guidance
Children focus on the use of kilo in units of length and mass.
They understand that kilo means thousand. They convert from
metres to kilometres, grams to kilograms and vice versa.
Children draw on their fraction knowledge to convert from
fractions to decimals. They deepen their understanding by
comparing measurements in different units.

Reasoning and Problem Solving
Laura buys 3,500 grams of potatoes and
1,500 grams of carrots.
Laura receives
8 p change.
Tiegan is converting measurements.
She says:
‘ I have divided by 1,000 to convert the
measurements.’
Which conversions could Tiegan have
completed?
She pays with a £5 note.
How much change does she get?
