This worksheet clearly explains the 4 spelling rules for adding
-ed to verbs and provides practice. While the narrative portions
may be too advanced for beginners, the simple formulas and
examples make it easily understandable even for those just
learning the simple past tense. It also works well as a review
for intermediate or higher students. Answer key on 2nd page.
This worksheet may be used alone, but was designed in
conjunction with a PowerPoint of the same name.
