If children have never been exposed to using phonics or to much counting, before starting in school, it will take longer for them to 'get it'. Children who have done some of these things in nursery or pre-school will have an advantage.
Some Cbeebies programmes, such as Alphablocks, can help with understanding and learning.
If she has all her individual sounds securely learnt, it shouldn't be too big a step to start putting two sounds together. I don't know if the Scots accent makes these things more difficult for children, but there obviously is a difference in pronunciation 'south of the border'.
If you look in the MN book reviews, 'Children's educational books and courses' the Oxford Phonics Spelling Dictionary would probably be useful, as it gives lots of hints on learning sounds.
For numeracy, do lots of counting and grouping objects, Lego, dolls, biscuits etc. Gaining an understanding of the 'number of things' is more important than just being able to write numerals correctly, and that can be a later stage.
For writing letters and numbers, have lots of paper and chunky pens, or a white board and 'dry wipe' pens that rub off easily. Or do large 'finger writing' in a thin layer of sand or flour on a tray.
Try and keep things 'fun' and relaxed, and avoid 'hard work'. Give plenty of praise.
