I have been designing resources for many years as I worked with preschool and primary age youngsters with delayed or impaired speech and language skills. The resources using symbols are free. My latest resources which I have illustrated are extra tasks based on Marion Blank's Language Levels (previous ones have been free). They can be used with groups of mixed language ability and are reasonably priced.
