Educational games have been considered to attract learner's interest for learning and the gamification of trainings for reading and writing has been also developed. However, from the nature that the phonological awareness trainings are mostly orally carried out, the gamification using information systems becomes hard. Thus we have considered that visual presentation of character strings using on the PC screen can attract children's interest and developed original learning support softwares. We have carried out these lerning support softwares for four children with developmental dyslexia, and we have cofirmed that children with weakness in character can play these learning support softwares.
