Linkage

Fractions:

There is a very close relationship between fractions and decimals. Each is a different

way of partitioning a unit. As fractions are generally easier to visualise, they usually precede

decimals in the order of learning.

Integration

SESE Geography:

Investigation skills, many scientific and geographical investigations involve

interpreting readouts from electronic displays (dials, meters, etc.), some of which include a decimal

point (e.g. weighing scales, fuel pump, electricity meter, electronic timer and range finder).

Maths at home/parental involvement

Look at the electricity/gas/water meters – does the display have a decimal point? Examine the

milometer in the car – does it show 1 tenth of a kilometre (sometimes in different colour)?
