This page has the supportive materials for phonics, including powerpoints, activities, games, worksheets and mini-books.
I recommend going through the Phase 4 material first, and if your child is secure with these, then move on to Phase 5. Please note though that Phase 5 is a big jump as it covers the Year 1 curriculum and will therefore not be appropriate for every child.
Don't forget you can still use these apps and free websites for phonics games:
