This measurement and geometry lesson focuses on finding the perimeter of a rectangle. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students read the problem to find the rectangle's length and width. Then, they substitute the rectangle's length and width into the perimeter formula and compute the perimeter. Finally, they label the answer with the correct unit of measurement. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
