Twinkl is a site of wonderful free resources along the lines of Mrs. Pancake. It is still very much under development, but every time I check back there is something new.
The resources come into the categories of literacy, numeracy, themes, signs and labels and management and behavior. Under Management and Behavior it looks like they have saved a space for SEN and PSHE (special educational needs and personal safety and health education). I can't wait to see what they add there.
