[senco-forum] b d confusion

Hello, as a learning literacy support teacher I have got a new pupil (aged 14) today who is confusing b and p in her spelling.  Not sure yet whether she can hear the difference but nothing noticeable in her reading as yet.  Can any helpful person give me some ideas and/or addresses of free resources in form of worksheets or games which I can use with her?

Thanks
