Presentation Transcript

In a field lives a population of rare Grasshoppers. The field is a square 100m by 100m. The Grasshopper International Trust (GIT) plan to carry out a survey to discover how many Grasshoppers live in the field.

The GIT are very short-staffed at the moment

due to the ‘Cricket Crunch’ and can’t survey the

whole field. They decide to break the field in to

smaller squares as shown:
