* This activity could be an introduction to algebraic rules.
* When I was at school Algebra was a topic on its own, often not related to anything real or "concrete". To me, Algebra is about generalisations of patterns and numbers around us.
* "Rules" we may have learnt about numbers are the beginning of Algebra. e.g. When we muliply a number by 10 we shift the numbers one place to the left and put a '0' in the 'ones' place, NOT 'Add a Zero' as adding zero doesn't change the number!!!!
* We want and need to students who understand and can apply those understandings to other situations. This means not just teaching rules nand short cuts but using investigations and thinking to develop understanding.
