This unit includes the unit for Grade 3 in case you want to review them with some students. I have tried to make them interesting to the older student while reasonably doable for the younger student.
These exercises are about the commas and quotation marks. There are also exercises on hyphens to make hyphenated words and for hyphenating words at the end of a line, since they learn about prefixes, roots and suffixes in Grade 3. This unit includes some grammar on the simple sentences that students read and write up to Grade 4 because these lesson cover also the use of the comma in compound sentences. The test at the end of the unit covers all of the punctuation marks taught up to Grade 6.
As with my other works, the answer pages show the student exactly what the answer would look like. Where the student is asked to express his own ideas, answers will vary, of course.
