Lots of credit needed to go to Mat_Harte for making this resource (https://www.tes.com/teaching-resource/slow-writing-cue-cards-11076882) which has inspired mine.
These are differentiated support cards which could be used in Y4-6. Differentiated three ways:
Good - for LA writers
Super - for MA writers
Amazing - for HA writers
If you are unfamiliar with slow writing then read the following blogs first before trying this!
