First Phonics is a series of graded activity books. It helps children to learn the basic sounds & spelling patterns required for reading & writing. First Phonics Book 4 reinforces children's understanding of letter blends (such as 'tr' & 'sl') & single sounds made by more than one letter ('sh' 'ch' & 'th'). This book is suitable for children making the transition from the Early Years Foundation Stage to Key Stage 1 & those already in Key Stage 1 who need further practice.
