Here we go!
My two absolutely favourite books for N and R maths are still BEAM's MiniMaths 1 & 2 (note - it doesn't matter which one you buy as Kim had too many ideas for one book and they are not aligned to yr grp or harder or easier!). I have not met a single N and R teacher who can't integrate these into their planning and use them to develop young children's mathematical thinking appropriately: https://www.amazon.co.uk/MiniMaths-1-Level-Beam/dp/1874099642
I don't know of any N maths curricula as such, and I would be v wary of any that are curricula for older children being watered or pushed down into R or N (eg white rose).
Sue Gifford's book is still one of the most important and relevant in N and R maths, and essential in considering research when pulling together a curriculum: https://www.amazon.co.uk/Teaching-mathematics-3-5-developing-foundation/dp/0335216862
The E years NRich resources are written by Sue and her colleagues (involvement alert- including me!), are well-trialled; some are more relavant for R than N.
'Numbers and Patterns' is still useful and free: http://webarchive.nationalarchives.gov.uk/20110202103440/https://nationalstrategies.standards.dcsf.gov.uk/node/273401.
And online look at Erikson materials (both of these based in the USA) - absolutely excellent: https://earlymath.erikson.edu ; and the work by Clements and Samara: https://www.learningtrajectories.org - which looks dull but I have found incredibly useful in looking at the development of children's thinking and understandings.
I hope some of this helps. Helen Williams, @helenjwc
