Retrofit the existing lesson of adding three numbers to include word problem applications.

This number sense lesson focuses on determining if a number is prime or composite. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students read the number. Then, they determine if it is composite or prime by trying to divide by either 2, 3, 5, or 7. Finally, students justify their answer. In addition to the lesson, there are eight pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items.
