I purchased these books for my daughter over the summer holidays to help her continue her reading skills during the 6weeks off school.These books are great and a fantastic value for money as most schools are using the Oxford tree at school I feel as a parent is important to carry on the learning at home.My daughter is given 2 books 1/2 weeks to take away from school and read at home and after 2 days she’s bored of reading the same books so this collection gives her many other books to choose from and stops her being bored of reading and also still continues to learn with the same reading level and range used at school.These books are levels 4-6 which is the levels used in year 1.I would definitely recommend these books to any parent and I will most certainly continue to buy all other levels of the Oxford tree as she outgrows these books.
