2. In a SATs Paper B you might be asked to look at a group of
shaded shapes and decide which ones are equivalent to a
given fraction and which ones aren’t:

3. For example: Here are 4 diagrams. Put a tick by the diagram
if exactly ½ of it is shaded. Put a cross if it is not.
Firstly count up the number of tiles on the grid.
There are 30.

4. First, work out how much of the fraction is shaded. See
presentation 1, if you are not sure what to do.
