This activity is about converting areas from smaller units to larger units and from larger units to smaller units.

Work out the areas of the above squares using different units.

1 cm x 1 cm = 1 cm² or 10 mm x 10 mm = 100 cm²

1 cm² = 100 mm²

1 m x 1 m = 1 m² or 100 cm x 100 cm = 10,000 cm²

1 m² = 10,000 cm²

1 km x 1 km = 1 km² or 1,000 m x 1,000 m = 1,000,000 m² 

1 km² = 1,000,000 m²

Let's give it a go!
