At least 1 in 4 children are not reaching the 'self-teaching' phase (1995) even after two years of systematic, synthetic phonics instruction (and testing) in the UK

You can choose to get them to this phase earlier - when 3 - 6 years old - or use these activities to give these children what they missed, and why not in the 'orthographic mapping' stage when in KS2 (7-11).
