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!
