       "I will never teach factoring the old way again!".

One teacher has developed a sophisticated programme for introducing her learners to
algebraic thinking.  Right from the beginning she uses an area diagram (rectangle) for

For example

Here is a display of work by one of her classes: details more visible below.

The teacher uses a general question for exploration which provokes learners into working on rearrangements and
rehearsing the use iof the diagrams to express areas as algebraic expressions:
