How do we measure the perimeter or area? 

Can we convert those measurements?

 

Let's try converting our measurements 

• Convert 120 mm to cm.

• Convert 455 mm to cm.

• Convert 8 cm to mm.

 

Centimetres to Metres (cm → m)

1. Convert 350 cm to metres.

2. Convert 99 cm to metres.

3. Convert 1230 cm to metres.

Metres to Kilometres (m → km)

1. Convert 5000 m to kilometres.

2. Convert 850 m to kilometres.

3. Convert 12,400 m to kilometres.

Let's grab our whiteboards and have a practice. 

 

 

Area 

How do we calculate the area?

 

 

Let's try together!
