The official app for the Sounds-Write Initial Code phonics programme, for learning to read and spell in English. ******* IPAD ONLY ******* This app is currently unavailable on the iPhone because of the writing element of the app. For young children to become fluent readers and spellers they need to rehearse and consolidate what they are learning. It is this, repeated over and over again, that enables their access to alphabetic code knowledge and skills to become totally automatic and internalised processes. This app offers a variety of activities to develop the skills of blending and segmenting, sound spelling correspondence, word reading and writing and some sentences reading and writing. The app has been designed to introduce all the sound-spelling correspondences your child(ren) needs to learn to put them well on the way to learning to read and write. Each unit will be locked until the child has completed enough of the current unit to be able to progress. For more information on the Sounds-Write programme please visit www.sounds-write.co.uk
