Using Units of Measurement
It’s important to use the correct unit of measurement when estimating the
length, mass or capacity of something.
When estimating quantities of an object you don’t know, try to think of some
familiar objects that you know and compare them. For example, if you know
that an average-sized pear is 100 g, then if you had a peach of a similar size,
you’d know that its size should be measured in grams.
Equipment for measuring
For measuring length, we usually use a ruler of some sort. For larger
lengths, there are ‘rolling rulers’.
For measuring mass, we can use weighing scales of different sizes.
For measuring capacities, we can use measuring cylinders or measuring
When reading measurements, it is important that you first take a look at the
units of the equipment and how much each division is worth. You can then
count up until you reach the marker.
