For Year 4, I would concentrate on the basic, please have a look at AE books - they have the shown the techniques really well, may be you can try with one first.
When she is in year 5 it will be good to try variety of papers from Bond, CGP and 1st past the post. i haven't used Bond Online too much but i have found http://www.11plusdiy.co.uk/
very helpful when DD was year 5, Autumn/Spring Term.
For VR - Susan Daughtery Technique books are really good.
Wish someone had recommended these to me when we first started.
