Measure Compare and Order Shapes and Objects Using Familiar Units (3)

Measure, order and compare objects using familiar metric units of length, mass and capacity (ACMMG061)

LO: To measure, compare and order shapes and objects.

Know:

  • the basic metric units of measurement.

  • how to use scaled instruments to measure objects.

  • the definition of ascending and descending order.

Understand:

  • that we can use formal units to measure, order and compare shapes and objects based on length, area, volume, capacity and mass.

  • that using common units of measurement increase accuracy and facilitates communication.

Do:

  • I can measure, order and compare shapes and objects based on length, area, volume, capacity and mass using formal units.

Length

Length measurements are used to measure how long, how tall or how far apart objects are.

We use special units to help measure the length of an object, they are millimetres (mm), centimetres (cm), metres (m) and kilometres (km).

Area

Area measurements are used to measure the amount of space a 2-D object takes up.

We use special units to help us measure the area of an object, they are similar to the ones used in length, but because they are 2 dimensional, we add a squared sign after the units.

Millimetres squared, centimetres squared, metres squared and kilometres squared.

Volume

Volume measurements are used to measure the amount of space a 3-D object takes up.

We use special units to help us measure the volume of an object, they are similar to the ones used in length, but because they are 3 dimensional, we add a cubed sign after the units.

Millimetres cubed, centimetres cubed, metres cubed and kilometres cubed.

Capacity

Capacity measurements are used to measure how much an object can maximally hold.

We use special units to help us measure the capacity of an object, they are millilitres (ml), litres(l), and kilolitres(kl).
