The Education Hub is developing Early Years advice which can be found here: (https://www.theeducationhub.org.nz/research/). A number of these show how the culture of indigenous people can be integrated into early years teaching.
For an example of an initiative set up to support teachers managing large class sizes, see VSO’s successful experiment with small group use of Ipads to provide personalised tuition at the child’s own level. Email enquiry@vsoint.org for further information.
Each community will have songs, rhymes and games which are used to teach children about the community and the environment they are living in. New songs/rhymes may be needed to explain the world children find themselves in.
