There's nothing whizz bang or whistles and bells about it. Students aren't inspired as they walk into the room, there's usually a bit of grumbling (oh no not this again) but their engagement builds gradually as they have to think for themselves mathematically.
It's effortless to set up (just 4 letters and 2 numbers on the board). I like the fact that I can spend my time listening to students and helping them give voice to their personal journeys into understanding primitive structures for mathematics rather than on class management.
This task rests easily with there being a little off task chat and it taking some students a minute or two to properly engage. As I've said before I've not taught in schools where there have been high standards of behaviour and I have never had the luxury of expecting all my students to come to my classes bright-eyed, bushy-tailed and well behaved. I've had to learn to take my students from being badly behaved to being fully engaged and therefore on task through the way I teach and the type of task I use rather than through demanding that they behave well before I start to teach.
It's important to understand that this task will become more powerful for you as you use it with more classes. You will gradually become aware of a wider and wider variety of structures that students use to support their thinking and as you become aware of them you become better at spotting what it is that a students is struggling to explain and at helping them to express it clearly to their peers. I think you will be surprised how your own thinking expands and takes you in the direction of confidently using flexibly the wide range of structures the teachers in Liping Ma's book used for calculation.
Is this the last post on this topic? Maybe not. Maybe you or I will come back with new ideas stimulated by this task. I hope so. Thanks to all who have asked questions. Please keep them coming!
