School are looking at having a uniform set of numercay displays up in class, to help children remember how to use various calculation methods for each of the four operations. I have been charged with coming up with a 'corporate standard' that will show progression throughout the years, in accordance with the school's calculation policy. Does anyone have something along similar lines (providing the above makes sense after 3 lots of marking) up in their school? Was it produced in house or is there something available off the shelf please? Not having much success with Google... Many thanks for any help.
