Five worksheets that take turns through the activities. Pages 1 and 4: students decide whether each sentence needs a comma before the conjunction. Pages 2 and 5: students write the comma in each compound sentence. Page 3: students join two sentences with a comma and the conjunction in the box. Every answer is worked out from the sentences themselves, and the answer keys mark each one.
Cover the conjunction with a finger. If a whole sentence stands on each side, it needs a comma.
Write two short sentences about your day and join them with a comma and and, but, or so.
A comma before and, but, or, or so when it joins two sentences, and no comma when one subject does two things. Students decide whether a sentence needs a comma, add it, and join sentences.
