This geometry lesson covers identifying two-dimensional shapes by their attributes. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will describe the attributes of a shape that are always true and sometimes true, and then match various shapes to the correct bin. Shapes identified are triangles, rectangles, squares, circles, pentagons, and hexagons.

This measurement and geometry lesson focuses on using a property of triangles to solve for unknown angles. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students list the given angle measurements, then solve for the unknown angle by adding the given angle measurements and subtracting the sum from 180 degrees. Finally, they interpret the measurement of the angle. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.

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.

This math lesson teaches students how to use the SAS, SSS, ASA and AAS postulates/theorem to determine whether two triangles are congruent. The lesson includes research-based strategies and strategic questions that prepare students for standardized assessments. In this lesson, students will identify given information and determine which postulate or theorems apply, and then use it to determine whether a second triangle is congruent. In addition to the lesson, there are two pages of independent practice and three pages of periodic review with questions modeled after standardized assessments.

This math lesson teaches students how to apply the Pythagorean Theorem to find the unknown length of the side of a triangle. The lesson includes research-based strategies and strategic questions that prepare students for standardized assessments. In this lesson, students will identify the hypotenuse and two legs of a right triangle, then solve the Pythagorean Theorem for the missing value. In addition to the lesson, there are two pages of Independent Practice and six pages of Periodic Review with questions modeled after standardized assessments.
