Mental maths and algebra

Students are presented with two calculation ‘tricks’ involving squaring two digit numbers. They then use algebra to explore the reasons why the method works.

The short presentation can be used to show examples to illustrate each of the methods.

The teachers' notes outline the task and suggest that this could be used as a starter to work on completing the square. There is also a link to a video clip where the two methods are illustrated (around two minutes into the clip).
