Abstract in Afrikaans and English / This study was initiated when the researcher became aware of the problem that learners from low socio-economic environments tend to experience barriers to learning in numeracy and literacy. These barriers were identified in a class of Grade 1 learners through extensive literature study, after which the development, teaching and learning of numeracy and literacy in grade 1 were investigated. The researcher then developed intervention programmes for literacy and numeracy, each running for a period of six weeks, in order to overcome learners’ difficulties in these learning areas. Each programme was subdivided into three shorter programmes of two weeks each, which addressed different aspects of literacy and numeracy. Each sub-programme was supplemented by a schedule of daily activities in order to reinforce learning. Learners’ competence in literacy and numeracy was assessed before starting the programme and re-assessed at the end, using the same tests they had done at the beginning. Learners’ marks in both sets of tests were compared, which demonstrated their progress or non-progress after having participated in the intervention programmes. / Inleidend tot die studie word ‘n uiteensetting gegee van hoe die navorser bewus geword het van die navorsingsprobleem, wat as volg gestel word: Die navorser is bewus daarvan dat leerders uit ‘n lae sosio-ekonomiese milieu gewoonlik struikelblokke in leeraktiwiteite in gesyferdheid en geletterdheid ervaar. Deur literatuurstudie is die struikelblokke wat graad 1-leerders in geletterdheid en gesyferdheid ondervind, geïdentifiseer. Vervolgens is die ontwikkeling, onderrig en leer van geletterdheid en gesyferdheid volledig uiteengesit en intervensieprogramme in geletterdheid en gesyferdheid saamgestel om leerders se struikelblokke tydens leeraktiwiteite te bowe te kom. Drie intervensieprogramme in geletterdheid en drie in gesyferdheid is saamgestel, wat elk vir twee weke gevolg is. Volledige skedules van daaglikse aktiwiteite wat by elke program uitgevoer is, is ook ingesluit. Leerders se bedrewenheid in geletterdheid en gesyferdheid is geassesseer voor daar met die programme begin is. Na afloop van die intervensieprogramme het leerders weer dieselfde toetse afgelê waardeur hulle vordering of nie-vordering bepaal kon word. Verskeie tabelle is saamgestel wat leerders se vordering aantoon. / Educational Studies / M. Ed. (Sielkundige Opvoedkunde)
