Step 10 Objective

Examine critically, improve and justify the choice of mathematical presentation, explaining features selected.


Examples of what pupils should know and be able to do

a diagram with a two by two grid and a two by three grid

Shading Squares
There are six different ways to shade two squares in this shape. Can you find them all?

 

What about this shape?

How many ways are there?

Try using different rectangles made up of more squares.

Try shading three squares.

Examples drawn from Shading Squares

Develops and uses a procedure guaranteeing all of the ways of shading three squares in a given number of squares, making observations based on correct results. They can systematically produce results for shading squares without drawing the diagrams.

Systematically produce results for shading squares.
