I also find literacy much easier, I do independent writing every Friday and use this, so I can see that they know something rather than assessing them the day I teach it. So in a way I'm using summative assessment for APP. I do daily assessment as well, formative, that leads my planning. I find collecting evidence for Maths so much more difficult. The only way is to ask several children questions in OM starter time and note answers. How else do I collect evidence to show they know rather than they can the day I teach it?
