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 measure, order and compare shapes and objects based on length, area, volume, capacity and mass.

Do:

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

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.

Teaching Ideas for Volume

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).

Teaching Ideas for Capacity

Mass

Mass measurements are used to measure how much material there is in an object. It is sometimes confused with weight, which is how much pull gravity has on an object.

We use special units to help us measure the capacity of an object, they are milligrams (mg), grams (g) and kilograms (kg).
