Here is a set of diagraph worksheets for Ch, Sh and Th. I have made seperate pdfs for British and American English, because words such as chips and torch required different pictures. I have also included two sets of almost identical worksheets in each pdf, some more guided for early writers and others to practice spelling for more confident writers.
* I have altered the files to fix the formatting issues. Please download the new files if you downloaded the previous misaligned pdfs.
