Breakthrough to Literacy is a comprehensive mother-tongue literacy programme for the first three years of schooling that incorporates learner-centred and language experience approaches. This combined method utilises the aural and oral language skills the child brings into the classroom from home as the basis for learning to read and write. In 2019, Molteno reviewed and revised the BTL Grade 1 programme in seven African languages: Sepedi, Tshivenḓa, Xitsonga, Setswana, isiNdebele, isiZulu and isiXhosa. The BTL programme includes conversation posters, readers, Big Books, phonics friezes, Learner and Teacher Sentence Makers, Learner Workbooks, and Teacher Guides. Currently, BTL isiZulu, BTL Setswana, and BTL Siswati are listed on the Department of Basic Education’s National Catalogue.
