I have been asked a couple of threads to suggest some decodable readers so, rather than keep typing out a list I thought I would start a thread and just do the list once!
In no particular order:
Fold-it books and King Wizzit www.syntheticphonics.net
Jolly Readers www.jollylearning.co.uk
Read Write Inc readers www.ruthmiskinliteracy.com
Big Cat Phonics www.collinseducation.com
Sounds~Write Reading books www,sounds-write.co.uk
Rigby Star Phonics www.harcourt.co.uk
BRI www.piperbooks.co.uk
Jelly and Bean www.jellyandbean.co.uk
Dandelion Readers www.phonicbooks.co.uk
Oxford Reading Tree Songbirds and Floppy's Phonics www.ukcatalogue.oup.com (OUP also publish Ruth Miskin books)
The only ones on this list that I am familiar with (because I am secondary) are Jelly & Bean, which I really like, and BRI, which is a complete 'learn to read' scheme in itself, but can be used alongside a phonics programme.
I'm sure that some of these are obtainable in bookshops and you may find them cheap through Amazon.
