Learning about area and perimeter...

In maths we are learning to find and compare the area perimeter.  We have been working together to make discoveries about area and perimeter.  One of our questions was: Can we find a rectangle where the area and the perimeter are the same?  We tried a lot of things, and many of us couldn't find one.  Three children managed to discover that a rectangle 6cm by 3 cm does actually have a perimeter and area that is the same - 18cm.  What a discovery!
