This apostrophes lesson and practice for grades 4–9 teaches students how to use apostrophes correctly in contractions and possessives. Designed for teachers, homeschoolers, and tutors, it uses simple rules, clear examples, and targeted practice to build confidence and accuracy.

This lesson can be used for upper elementary students, or for secondary students who have not mastered the basic usage rules and need more practice.
