This math lesson teaches students how to use the Triangle Inequality theorem to determine the possible range of values for an unknown side of a triangle. The lesson includes research-based strategies and strategic questions that prepare students for standardized assessments. In this lesson, students will calculate the sum and difference of the two known sides of the triangle and recognize that the unknown side must have a value between the two. In addition to the lesson, there are two pages of independent practice and nine pages of periodic review with questions modeled after standardized assessments.
