Hi dizzy hope you're getting to grips with this.
Caz was right on the previous page, church would be /ch/ /ur/ /ch/ (3 sounds). With synthetic phonics you are selecting the sounds that compose each word and looking at the letters which make those sounds. For some it will be a single letter, for others such as /ay/ /th/ /sh/ etc you will need 2 letters, and for some sounds such as the /j/ in 'badge' you will need 3! It is tricky trying to distinguish what you can hear from what you can see. Thinking about which parts of your speech apparatus that you use can help distinguish one phoneme from another but it does take practise! For example: is you say the blend 'sp' you will articulate 2 phonemes - /s/ using your tongue at the back of your teeth, and /p/ using your lips.
Takes a bit of practise but worth doing to improve your own phonemic awareness! Good luck with it all, hope that helps a bit. If not - I hope it hasn't confused you further!!
