My friend Lauren, a speech pathologist in training, has just sent me this link to the 'Free language Stuff ' website. Paul Morris is a speech pathologist with a special interest in teaching language. His site has over 200 free learning activities in worksheet form.
While I am not a big fan of worksheets, especially when a teacher goes to the copier and hits 25 so that s/he has enough of the same worksheet for every student in the class ; I am not opposed to providing resources in a variety of ways, to meet the individual needs of students during each lesson.
Check it out. You might just save yourself a lot of time and find exactly what you have been looking for.
