To secure Word Mapping Mastery®, children need to move into the self-teaching phase, where they can independently work out and store new words. This phase is often kick-started by the core code introduced through phonics, but it goes beyond taught correspondences as learners begin to map words for themselves. Crucially, this self-teaching happens in both directions, from print to speech and from speech to print, strengthening both reading and spelling. We will share a range of activities that support this bidirectional word mapping, helping children build secure, flexible, and lasting orthographic knowledge.
