We explore the potential of merging numeracy and literacy, through using number stories to stimulate mathematical engagement with young, marginalized learners in their communities. Our data emerges from the Family Maths Storytime Programme (FMSP) run in partnership with teachers in two South African schools. The FMSP conducted sessions with caregivers of pre-Grade 1 learners that focused on supporting mathematical talk in the home centred around four number storybooks with linked activities and games. Drawing on Bourdieu's notion of habitus and other socio-cultural theories emphasising opportunities for talk and reasoning for learning we explore: Did the FMSP enable the integration of home and school numeracy and literacy practices? If so, what evidence is there of such integrated practices? What is the nature of the described practices? Our analysis focuses on 20 caregiver interviews following their participation in the FMSP that was initially run after school in two English medium pre-Grade 1 classrooms. NVivo coding highlighted key themes across interviews. The findings show how modelling engagement with merged literacy and numeracy practices in the programme enabled changing practices, dispositions, and forms of capital in relation to engaging with these in the home. We highlight how supporting home-based and story inspired engagement with marginalised learners supports equity goals in contexts where learners from indigenous backgrounds often begin and remain mathematically behind grade expectations in school.
