Hi again Hellelujah -
If you are still following this 'thread' and further to my earlier mention of the the Oxford Phonics Spelling Dictionary:
I have now purchased this book from Amazon, and it really is very good - better than I anticipated in some ways.
You can see sample pages on the Amazon site, and words are listed in order of the initial SOUND, and not necessarily the initial LETTER.
Thus, the book starts with 's' sounds, but after words that actually start with the letter 's', come words like: celebrate, celery, central, centre; cinema, circle, city; cycle, cylinder; scene, science, scissors; ie, words that SOUND as if they should start with 's' but don't!
Still on the 's' sound come words with the sound in the MIDDLE or END of the word, thus: class, lesson; bounce, dance; chase, horse; castle, fasten, etc.
On the pages of 'f' sounds as well as words that start with the letter 'f', come the 'ph' words: phone, photo, phrase, physical. Then come words with the 'f' sound in the middle or end: cliff, coffee, cuff, fluffy; cough, enough, laugh, rough.
I appreciate you are wanting to help KS2 pupils, but I think the way information is presented in this book might well focus their attention on how words are spelled. It also gives plurals, and different tenses for verbs: forgive, forgives, forgiving, forgave, forgiven.
It might sound as though I am enthusing like an OUP salesman, but I assure you I have no agenda other than, as a retired TA, to still support pupils and teachers via MN whenever I am able.
Although this is only one book, and not a 'scheme', I think it is well presented and accessible, and that you could easily construct your work plans around it.
I'll repeat the link here, and wish you good luck with using it!
