This package includes three lesson plans focusing on using three strategies for solving addition and subtractions problems:

· Using place value

· Using the commutative and associative properties

· Using the relationship between addition and subtraction.

Each lesson plan uses animation as the springboard into an activity. While I include the Mathematics Georgia Standards of Excellence (GSE), all lessons are written to be used with matching state and national standards that include real-world applications.

The first lesson is for introducing using three strategies for solving addition and subtraction problems with multi-digit numbers. It includes a graphic organizer, practice with a gallery walk for peer review, and a concluding discussion. The second lesson focuses on practicing solving these types of problems using the three strategies focusing on careers. The collaborative activity includes 40 high-interest careers, a presentation component, and a concluding discussion. It includes a PowerPoint with the presentation’s expectations. The third lesson focuses on quickly practicing using two of the three strategies (the two properties and the relationship) in a student-centered activity. The activity is designed to be easily repeated throughout the school year for continued practice. Over 160 additional practice problems are included in the package!
