=Stage 1 - Identify Desired Results= Geometric Figures Grade 9-Diploma 1 Students justify statements about polygons and solve problems. ||
 * **Establish Goals (MLR):** **(G)** ||
 * Maine Learning Results: Mathematics-C. Geometry

//What understandings are desired?//
• when making triangle calculations students can estimate to guess and check. • you can find side lengths of right triangles using the Pythagorean Theorem. ||
 * **//Students will understand that://** **(U)** ||
 * • all shapes have area and three dimensional shapes have volume.

//What essential questions will be considered?//
• Is there a difference between certain types of triangles and there side lengths and how can I tell them? • Why is the Pythagorean Theorem important and how can I use it? ||
 * **Essential Questions:** **(Q)** ||
 * • What is the difference between area and volume and how do you find area or volume?

//What key knowledge and skills will students acquire as a result of this unit?//
• Terminology for: Shape names, congruence, scalene, obtuse, acute (triangles), right triangle • Definitions of theorems, triangles, shapes || • demonstrate they know how to use the Pythagorean Theorem. • make sense of triangles with congruence lines of them • use the Pythagorean Theorem to find the length of a missing side of a triangle. • compare and contrast area and volume. • relate the area's of shapes to the volume of three dimensional shapes. • recognize the different types of triangles ||
 * **//Students will know://** **(K)** || **//Students will be able to://** **(S)** ||
 * • Formulas for: Area (for many shapes), Volume (for many shapes), the Pythagorean Theorem, and degrees of angles.
