Grammar in 3rd grade

Third grade is where grammar turns to the sentence as a whole. Students find the subject and the predicate, make the verb agree with its subject, join ideas with conjunctions and punctuate what they write with commas and quotation marks. Every set here is a lesson in three parts: a one-page explanation, guided practice and independent practice.

Topics overlap between grades on purpose. A set marked for grades 2 to 3 appears on both pages, so you can use it for first teaching in one year and review in the next.
